I've been with my girl for 3 years we been through ups and down she even told me she cheated on me I am fairly a nice guy she is a hot head but I love her. Recently I went to see her and she didn't respond to my needs I mean I wanted some one on one time and she thinks all I want is sex well yeah at the time I did hell we only see each other once a month so I didn't think it would be a big deal well that started a big argument and I told her that why is it a big deal I'm helping you and doing for you and you would rather give it to somebody else. Well needless to say I texted her and said I was sorry but she never replied its been a week and no return to any of my calls hell I just get the answering service. I just want to know if its to late I feel like 3 years has gone in the blink of an eye. What can I do to save it or is it to late

Sounds like it's over to me.

She cheats, you only see her once a month and when you do she doesn't want to be with you.

I'd say the writing is on the wall. Sorry.
