everything is going so well

But I'm still stuck in the past. The way he handled things, him talking to girls and asking them to hang out (I don't think they ever did. From what I can tell). I looked through his phone the Other day when he was sleeping to see what he was up to when we were broken up. I know I shouldn't have cause it doesn't matter. There was a picture of spaghetti he bought from a restaurant lol for a dinner date I guess but the girl stood him up. He asked another girl to hang out but she said she just started dating someone. Ugh I shouldn't have looked. Should I just focus on the fact that he came back to me and said he missed me, loves me, needs me in his life?
