And he hasnt still called me! So like last summer around this time he stoped calling me and when out with a chick name morena but we got back together! And it seems like this is happening again and I dont want it to my heart still hurts every time I think about it and im just so scared it will happen again and I dont want to break up beacause I love him to death! So what should I do about him and before we started going out I miss the way I use to be I miss my old life and it changed so much! Please help and give me good advice!! It would really help!!!
