Does my ex still love me?

I had a long distance relationship with my ex boyfriend for 9 months we were so in love and he s faithful to me and so was I we had a couple of problems towards the end of our relationship he asked me for a break we got into a huge fight for him asking for a break. I ended up cursing him out of anger and he broke up with me. We were never this disrespectful to one another like that after our break up he would call to check up on me every week and than I found out he started dTing another girl that was dating his best friend a month before he still asks about me and lately he's been telling me how much he misses me and loos at my instagram and tweets. Does he still care for me ? Why is he doing this?
