Um... talk to him? Tell him? I don't mean to be crass but we do understand. It is usually pride that causes us to start fights or what not.
Two things, first a thought: if your kisses won't hold the man you love
Then your tears won't bring him back. You've broke up with him. If he let you go, than he doesn't want you. You're done. Move on.
Second. I was in the, "If I know why the sex has stopped then I am okay, because it will get better after the reason has been addressed." It didn't. Even when the reason has been addressed it is hard to get back to that level of intimacy.
There are a few mental things that are going on here as well on your part. You're stuck in a "Even if I am a little unhappy here it is better than being alone." rut. A lot of people tend to stay in a dysfunctional relationship mostly because it is better than giving in and being forever alone, partially consumed after death by your 20 cats because no one knew you were dead. It feels that like you're not really comfortable with yourself as a singular person but only as a piece of something else; Ie, relationship. You're giving too much of yourself away to be part of this relationship. This is evident in the "I'm okay with..." statements. Compromise is good, to a point.
Maybe I'm reading too much into this. Good luck.
