There could be a variety of reasons for her hot and cold behavior, and its hard to speculate what it might be. I would suggest continuing to text her but try to liven up the conversation topics whenever possible, and back away whenever she becomes cold so as to not end up overthinking and confronting her about it. Give her some room to ease back into this a step at a time, and try not to build up your expectations right now or get emotional if she doesn't respond the way you want her to.
Getting dumped sucks and when your boyfriend decides he doesn’t want you anymore it just tears you apart from the inside out. I feel for you but don’t worry because we are going to take a look at your breakup and figure out the best way to approach things. Again, I want to reiterate this point- don’t assume that the reason your ex boyfriend gave you for why he chose to break up is really why he decided to let you go. This may sound a bit mean, but you are going to have to be completely honest with yourself and possibly look at things that may make you uncomfortable.
HI Kim…thanks for stopping by. As I talk about in my ebook, Ex Boyfriend Recovery Pro, this whole focus on No Contact is just about getting him back, but its also very much about doing things for yourself in a realistic and pragmatic way so if it doesn’t work out, then you path into the future can (and will) be fulfilling. Be careful about reading too much into what guys say during and after a breakup. He may very well not know his feelings that well. He might think he does, but time has a way of telling us the truth about our relationships. To optimize your chances, take a look at some of the ebooks I have written which you can find on my website Menu/products link. Let me know how things go for you Kim!
