Girls do u think its ok if your husband ?

Have female friends and message. each other is that ok with you. Two weeks ago I ck our cell bill and they tex 30 time a day and when I told him he call her the next morning, I'm thinking to tell her that I may call. I was going to get out of our house with my 5 year old boy ( I'm 21 weeks prego 2) but my parents talk to him and he said he was going to change, but today I ck the bill again and he still doing it but he is the one calling her so its him...And girl is not that I'm insecure is just happen. Ok please answer good things cause I'm thinking of going home and ask him to get out, I can do this anymore I don't need all this drama right now. I just feel bad that my baby boy is always looking for him, but I need to be strong for me.
