me & my ex split up over 1 1/2 yrs ago because he had to switch schools. We would talk a few times every month & then it became once a month & then it was every few months but I never got over him. Recently we’ve been talking more & he told me he misses me & asked if its weird that he wanted to kiss me. We made plans to hang out & I was going to let him stay the night. The night he was going to come over he stopped answering his phone. Its been 4 days & silence. what should I do?
