Need some FRIENDLY advise?

Ok... so here is the skinny.... I am totaly and compleatly in love with my ex (A) ok so when i was with A he had some issues back home and he was told that he focuses to much on me and my daughter (not his child) but he loved us like we were his wife and kid, Well he calls me 1 day and tells me we need to talk ask if he can come over i say sure... he says i love you and hangs up 10 min later he is here and wont come inside (this is strange) so i go to his car and he stars by saying that his brother wants him to go to Nebraska and that he is upset because he seen that he has a GF over FB. so he said 1 imma delete you as my friend.... (WTF) then he say that i think i need my space and time to clear my head.. he said he not happy with himself... This left me in a Bawl fest

So then a few days later he wants to hang out... We Decide upon a FWB thing and it was going good till it was only at my place... then today i text him to see if we can do a movie(my treat) he says No so i ask why and he said because i said no and that's it... Then tells me to delete his # and thank you.... Do you think that he found someone else or hes pushing me away for some other reason...And should i delete his # or just not text or call for a few? Please don't be brutal i'm just looking for advise
