I have been with my boyfriend for 2 years. he has only recently told me that he's been feeling as though the 'spark' has gone between us, and he's not sure whether he wants a relationship. he has been really distant, i.e. he never really wants to see me, we hardly have sex anymore. it's really been having an affect on me knowing that he may not want to be with me anymore.
we decided to go on a break to see how he feels without me for a couple of weeks. I'm finding it hard to cope, we were together and happy and now all of a sudden he's gone for a while. if he decided he doesn't want to be with me at the end of this break, I don't know what I will do.
we are both young, and I feel that he just wants to be single and to do what he wants without feeling as though I'm there not allowing him to do whatever he wants. but he says that he doesn't want to be single and without me either.
I really don't know what to do about this.

thank you for any comments
