I'm confused, sad, depressed, lonely
My boyfriend is a drug addict
And a month ago he went to a rehab place, which is states away from where I live I love him and always will I'm really glad he's seeking help he has done it before but relapsed
Now he will be away for idk how long
And calls me now and than.

I feel bored and sad I'm a very anti-social/quiet kind of person
So no friends really.
Except one I've known him for a while,
I have no feelings for him whatsoever nor attracted to him
But he does he says he likes me a lot.

He knows my situation and understands
So he asks me to go out to places eat/skating/movies
I went with him and I want to go out again I want to have fun
To distract myself from being sad
But if my boyfriend knew he would be sad/upset
I'm not cheating because I do not like this guy
I'm not planning on telling my boyfriend

I don't know what to do. I want to be happy.
But I don't want this to affect my relationship.

I'm only 21yrs old

Any suggestions?
