No it's not right. How can you be expected to be physically intimate with someone who isn't talking to you, and when they are they are saying hurtful things. How can you be expected to be intimate when he handed back his ring and called it off??

I'm really sorry, but you have a choice here, go with what feels right to YOU. If he can't be bothered to care about you, your self injury or pain, the fact that this is your birthday, why should you be expected to take care of his sexual wants in return?

I think you need to start looking at what's good for you in this situation, what do you really want in your future.
