Me and my husband just got married on December 23, 2008 and before we got married he was mentally cheating?

on me so bad that i thought i was going to miscarry ur child and i have cried so many nights. he was on myspace and facebook flirting with so many girls. he even got some numbers and he told me that they were just his friends. and he even sent nude pics to 1 of the girls. he is in the navy and after he graduated bootcamp i found out he got a girl number in bootcamp. now he was flirting way before he went to bootcamp and he wrote me while he was in there saying he was a changed man. he told the girl from bootcamp he wanted to be with her. he is 22 and she is 29 and she has 3 kids. i have 3 but my youngest daughter is his child. but anyway. she told me he never told her abut me. i got over that and when he moved to fl. he was only there a week and got another girl number. i found out about all of this because i was snooping throw his things and i was hacking in his ms and fb accounts. we have been on good terms only for a week and i think its because he got in some trouble with the military police and the city police and he was at a point of wanting to kill his self. b4 this happened we had problems about money, he never wanted to give me money or let me know how much his checks were......we have deleted our myspace and facebook accounts because i told him we needed to cuz he couldnt do right. now i want my page back and i know he want his page 2 but im scared he is going to do the same thang over and im afraid to go through the pain......please help.....what should i do
