Cheating??

Jessica
I just found these messages on my fiancées phone.... Before i confront him over it I just want to make sure I'm not overreacting by packing my bags and leaving?? I'm currently 11wks wth our first child the child he wanted so badly and then he goes and does this! I know my hormones are all over the place and I know he'll say that too me, but I just want to make sure that it's not just me that thinks this is wrong?!
