Yeah, that’s a pretty huge dealbreaker.  I think the only thing you can really do is give yourself time. You’re going to have to let yourself grieve the breakup, and it’s going to hurt for a while. The grief will probably come in waves, but, over time, you will feel better.  In the meantime, let yourself feel sad, cry when you need to, and pick up some fun hobbies to help yourself feel better. It’s a really good idea to stop communicating in order to let yourselves detach from each other. That’ll help you get over thing more quickly.
