Struggling with cheating boyfriend

From my best friend:

I'm 42 years, healthy and decent lady, my partner is 47.
We've been together for 3 years, and we haven't had sex for almost 2 years. Although I exercise and have a nice body, he has no interest in sex whatsoever, and every time I try intimacy he gets very upset.
Last year, I had to spend one month away for work and he came to visit once. When I came back home I found a pack of Viagra empty and bought when I was away. I confronted him and he promised that he never cheated me, and he was trying the Viagra alone to see if he had any reaction, but it only gave him a big headache.

2 months ago, a found out that the cheated on me with a 23 years old girl that works at the same place. It was devastating. He said he had sex with her twice, and that happened when I was away. He beg me pardon, he promised he would never cheat again, he said he would do anything to are things work. He said he didn't work with her either and that he was only setting for the last year, but he never touched her again because he realized it was wrong, that he loves me with all his heart. That he took me for granted, that he'd do anything to make it up for all he the hurt he did to me.
They've been speaking for one year, I just found out because I saw her message popping up on his phone and decided to check. He spoke openly on a very sexual and nasty way. And he kept promising her, that they'll make it again soon. He said that his girlfriend was in town, but that he will arrange something soon.
On the last year, he started being very rude to me, he even called me 'f** bi**' once.

I decided to give him a second chance. But it has been 3 months, and he still doesn't show any interest in sex. I'm feel terrible and lost. I really don't know what to do.

I start suspecting that maybe he is still in touch with her.

Please I need an a advice.

Thanks everyone

I am afraid this does not look good and I suspect that you know what needs to be done, unless you really want to be treated in this way.

Time to move on. He is not worth the aggravation.

It's really a good thing there hasn't been any sex in so long, He might possible had contracted a STI and given it to your friend.

My advice to her... Dump him and move on.

For me, I'd rather be alone than be treated like this and pretty much played for a fool. It is not going to be easy, but she needs to get rid of him. Tell her she deserves someone who will treat her well and she's not going to find him staying with this idiot. So sorry this happened to your friend. And I will add that I would not feel bad giving this kind of advice to her as she needs someone who will be honest with her....the life she's living is riddled with uncertainty and pain. Who needs that?

If you're attractive and in good shape, you will eventually find someone whose needs match your own. Best wishes.

It is sad for me to see my friend like that. He claims that he has erection problems. But for me this sounds like bs. He doesn't work with my friends, but he does with that woman...

ok is it me...I am confused now??? I though we were talking about a woman friend???

I think he is playing you and you need to move on. He is not worth waiting. He is making you wait and for what? You don't owe him anything. I believe as long as you are at his beckon call, he will treat you whatever way he wants and continue to lie. You need to ask yourself how much are you worth?

It is a woman friend.. Spell check from iPad sorry

What it is confusing for me is the fact that he doesn't want to let her go. Why he keeps her, if he just wants to play?

Perhaps because he is using her for SEX!

If your reffering to him not wanting to let your friend go.. Then think of it this way.. he has a live in that is probably doing the cooking, cleaning , laundry and paying towards the bills if not most or all.... Why would he give that up? He wants to go cheat, I doubt he's looking for anything serious. If he wanted serious then I would think he would work hard to keep his current relationship healthy by whatever means necessary.

This isn't rocket science, It happens day in and day out by a good chunk of people on this spinning rock.

Life is too short. Move on. There are plenty of good guys out there who will treat you right. It's obvious you'll never find happiness with this loser.

So true! He's is a loser. I asked my friend to move to my house until she has her head straight. She showed me all the massages he sent to that woman, and it is disgusting.

I also find disgusting how certain girls are. How can you ask a guy to leave his gf home sleeping and come to have sex with you? I think my friend should let him go and start dating that sl**. That's what he deserves, they actually deserve each other.

A sexless relationship when you want to have sex... I'd tell you're friend to be grateful she's not married to this guy with kids, walk out and never look back. There are billions of people in the world and there is someone much better for her out there.

Absolutely!!

You deserve so much better. Been there too...best to you!

She's an amazing person and she deserves better.
