I took a break, but I truly loved my boyfriend I did it more because of his b.s. I think it can help in some cases but I am back with him and I'm still not happy. I think it could take a turn and help, but like I said sometimes the crap is still lingering on. If you truly love him I would pull back as well and not respond. A true break is no calls no text or seeing them. This is hard but it may open your eyes if this is what you truly want. If he's just taking a break because he can't decide maybe you should walk away now.
I really don't like "taking a break", that gives a guy a chance to act single while still having someone waiting for him. Maybe he does need space, maybe it's just physically? He still thinks about you a lot if he still texts you all the time. Always look your best around him, if he decides he doesn't want to be with you, his loss. Good luck woman.
