My boyfriend dumped me 3 days ago. Our relationship was very intense & we jumped into things really fast. We are from different worlds which is part of the allure, he's introduced me to things I never would have experienced on my own.
His so-called reason for ending this is that he wants to end things while they are going really well before he disappoints me. Although he also says that he sees some similar signs to past relationships & he doesn't want to go down that road again. He wants to end things before we end up hating each other. Save the friendship. Yet he still says he loves me & that being apart from me & hurting me like this is killing him. Neither one of us sleeps or eats. He also says that he has a lot of crap going on right now, none of which concerns me, and that he needs to sort out his life & doesn't want to be responsible for anyone else other than his son.

He knows how I feel. (he's the first guy I've felt this strongly about in 4 yrs - since my ex-finance & I ended things)
My question is... if I give him the time & space he needs to sort things out. & work on myself in the mean time. Do you think he will come back?

He may... He may not.
Usually when a guy ends up things out of nowhere is because he doesn't really see a future or he might be saying the truth and does have a lot of things to deal with at the moment. Which does make sense, because when someone is having problems, wouldn't you want your partner to be there and help you through?? (something to think about)
If he says that he can't eat or sleep, then why does he try to fix the situation
Is he still able to fix what he already broke?? One thing is no matter how much you care or love this person, if he decides to come back, think about it twice because you don't want to be someone he could leave and come back to whenever he wants, leaving you feeling like you are right now.

No one knows what the future holds, and what others will do. Moving on, is what you should do, and see what life has for you.
