I have been with my girlfriend for nearly 8 years now. At first the relationship was great.it has slowly dwindled off and it seems like she hates me most of the time. We never kiss or hug anymore and she says it's because she doesn't like it.its confusing to me as I am a very affectionate person. She always tells me I'm pissing her off and tells me to leave her alone.I would really like to fix it as I am unhappy a lot of the time around her because she always tells me to go away and to stop touching her.we hardly talk anymore and face opposite ways in bed.please help

What is keeping you together?

The other answer is "what's keeping you together". I am wondering the same thing.
You aren't married, thank goodness, and I would look elsewhere for another relationship. A good relationship should have respect, trust, faith, and a willingness to talk about anything. She doesn't have this anymore. Time to move out. I am 70 yrs old, a widower after 30 yrs of marriage, and am very grateful that I found a wonderful lady at that time. You will, too. Move on. I do wish you the best. and Happy New Year.
