Hello!!

I've come on here because I need some advice or at least some suggestions on where I turn. Sorry this may become a little long winded but I really would appreciate some help with this.

Me and my girlfriend (lets call her Lilly) have been together for about 2 years now.

We get on amazing. She makes me laugh so hard sometimes and in almost every way we are on the same wavelength. I've never experienced this before with any person in my life. She's kind, caring, great with my family, the list goes on. These are the reasons that are keeping us together...for now.

Even very early on I started getting signs of her deep insecurities. First time was when I invited her to a meal with some of my friends. One of my female housemates was there and I was joking around with her a bit during the evening. As simple as spinning my housemate on a chair. I appreciated Lilly was new to everyone so made sure I kept much of my attention on her. Lilly at the end of the night told me she thought something was going on between myself and my housemate (really nothing was) and that maybe I should be with her (she them stormed off and went home). I've never been in a relationship before where I've experienced a jealousy streak like this, but we got through it hoping to move on.

It's gone to the point now that she's admitted to looking through my phone messages and photos, calling me if I've been to the gym longer than usual, making me feel bad seeing certain friends because she doesn't trust them, analysing me when I might be quieter on a certain day, constantly smothering me and telling me she loves me so much it hurts sometimes.

It all got too much yesterday when we were invited to my friends birthday meal. She got angry and brought me a side when she believed the girl sat next to me was outrageously flirting with me (the girl in question was in a relationship herself and showing me a present her other half had bought her the other day!).

Today I've told her she needs help and that she needs to take responsibility for her issues or I will leave her.

She's fully aware of her insecurities and wants to do something about it, but the more I look at her the more broken as a person she looks. Sometimes I feel it would be better for her to not have this drama and start again. She's talked before about therapy but this time I out and out said I want her to take that route. This relationship is worth saving but I'm not really sure this can be fixed. Has anyone here felt like Lilly and got through it? Are there any ways I can help her? As you can imagine this all stems from her previous relationships and although she says she trusts me, deep down I don't think she trusts anyone. Just want to do what I can to help.

Thanks for reading!
