I am so confused, hurt and upset about my relationship. Me and my partner have been together nearly 3 years and I really thought he was 'the one.' We planned our lives together, moved in together and it was perfect. In the last 6 months, for no real reason that I can tell, my DP has started being pretty nasty to me. I think it is nasty - perhaps you can tell me if I am being unfair on him.
In the last 3 months, DP has cancelled events we planned together and with our friends, last minute, and said he needs to do overtime at work. When I had some severe dental work done last week at a dental hospital, I said I would really appreciate him being home as I needed some TLC, and he said he was too busy at work to do that and would be back late, again. When he works overtime he never lets me know until the last minute, and is really aggressive and offhand with me, and tells me not to pester him at work. When I get upset about any of this, he will get angry and defensive, and often just hangs up the phone on me. I had a job interview 2 months ago and he forgot about that - no call or text after it. He has started to not mention when he will be away at weekends, and let me know last minute and then I won't hear from him for hours and hours... his favorite excuse is that his battery has died. In bed he is very selfish, he's never gone down on me yet is happy to receive...and if he finishes before me, he cuddles me then goes to sleep. He tells me that I can use his car on x date, then at the last minute will tell me he's 'decided he's not ok with it,' and it's 'stressing him out.' This has left me car-less when I have arranged to see a friend and I am left to go via train - but makes my life quite difficult when arrangements have been made and I've placed reliance on being able to use the car.
In summary, I feel neglected, lost, lonely and very unhappy.
I've asked him what is going on and told him how unhappy I am, and he claims he has done nothing wrong, (though admits that not being there for me after the dental treatment was a bit shitty). I've asked if he still wants the relationship and he says yes. I've asked if he's unhappy about something else, or something at work, he says no, and says he chooses to work late. I also am 100% sure that there's nothing going on with anyone else - I've asked him about this in detail.
What to do?
