How to get someone back talking to you after being too clingy
Well, there is a man who I like ... and who liked me too and he doesn't deny that...he was first showing me his sympathy..then he needed to stay alone and think about things...and I couldn't understand this trying to communicate with him...i couldn't be patient and just wait, instead I was trying to know what's going on with him...he started to be busy all the time...stopped talk to me and I had to say hi to him first...and as more he got far from me I wanted to fix things and I started to be annoying I guess...i was asking him about his feelings and couldn't talk about anything except relationship...i guess I pushed him away by this...
so now he's just ignoring me...sometimes he answers if I write to him, but told me that I never leave him alone and don't give him chance to talk to me first...and that if he wanted to talk to me he would do that...just I m afraid he will never do this :(
i know that I can't force anyone to feel something to me or to want talk to me...but can I do something to fix this situation?
