I m with a boyfriend with PSTD and I feel so unloved for the past 6 months.
We even stopped making love for 3 weeks &...
This answer may not be particularly helpful, you might not get the answer you are looking for. I don't think there is a quick fix here. In my experience you cannot 'do' anything except reassure yourself that this is nothing to do with you. You need to look after yourself at the minute and don't get sucked into it. Perhaps your partner discussed breakup because he felt lowsy that he cannot meet your needs. I would say he certainly didn't mean it or want it. If you look at my post "sex and intimacy"
You will see in the replies, you are not alone, so many of us are in the same boat.
3 weeks (although while your living it, it seems it) isn't a long time, perhaps he is just going through a hard time. Just be careful not to put extra pressure on him by talking about it, if he's not ready to talk .. IME I have pushed him further away by trying to discuss something when the timing isn't right for him, so just be aware of that, be careful of the language you use also.. it's important not to make him feel guilty about it.
Sometimes I think when these things get you down the best thing is putting all your energy into making yourself happy and healthy. keep busy, see friends. Most importantly don't over think it. I sometimes used to let those negative thoughts creep in, before you know it your a blubbering mess and have a massive knock to your confidence. Don't allow that to happen.
It is not about you, it's not that he doesn't fancy you, or that he doesn't enjoy sex with you. He still loves you (the fact he would sacrifice his own happiness to 'let you go to find what you deserve', says that!)
I'm sorry I can't give you a magic fix, read that thread I mentioned, you'll see lots of us can relate. If you ever need to reach out to someone who understands contact me for a chat any time. (sometimes close friends or family can be hard to talk to because they don't understand) Big hugs to you!!
