When do I give up?

E
Ladies I have a question. When is enough enough? When do you stop fighting for the person you love. I have a dilemma because I am still completely in love with my "ex" and we said that we would talk at the end of summer. I've reached out to him multiple times and when asked he said "yes" he would like to talk. However -- I haven't heard from him for a couple of days and he hasn't said anything about meeting up to "talk". So do I send a text confessing my heart or should I just leave it be? My mind is telling me not to look desperate or crazy but my heart is telling me to do just that. -- what do I do? Should I fight to get him back?
