I miss him so much !!!!!!!

God i hate feeling like this so much.he text me yesterday to see how i was and asked could he call me so i said ok.when he called he asked what id been up to,had i seen my x and told me hes not getting back with his ex(yeah right).Then he said he misses me and said hes going away 4 a couple of days.then later he text me when i was in bed 4 quite a while. said he bets i look great now ive had my hair done,told me he does care 4 me and again that he misses me.I think hes maybe doing this because he wants to make himself feel better as he feels guilty.And of course i havent heard a thing today and he took the kids home so probably worked things out with her.why do i miss him so much?
