My bf left me 1 week ago because we were arguing too much lately and ive been insulting him several times.we both have going thru problems with personal life.4days after he said he misses me and ask if we could be together when things get better for us.I said no, u left me and its better to stay friends.after that I didnt hear from him so sunday I texted"thinkin of u hope you are doing good" he asked me to talk on fb but he lasted like 10-30minutes to answer every fb message so I left.since then I dont know about him.do you think he lost interest? What should I do? I already sent him something on sunday, so if he didnt catch"the sign"maybe he doesnt care anymore.I want him back.
