My husband go a message from messenger from a girl. He’s had a history about texting and messaging other girls one of those girl happened to be one of my cousins she didn’t know he and I were together and he didn’t know she was my cousin. My cousin told me that they had been texting each other and that he would try sexing her and would tell her thing at a person committed shouldn’t be telling her and ask for her to send him pictures of her. I confronted him about it and at first he tried to denying it then I told him she my cousin and he knew he was totally busted. But since we were only “dating” at the time I choose to move forward with our relationship. We got married and shortly after marriage I found out he was messaging another girl. He claims it was innocent, the girl and him had a mutual friend that killed her self some years ago and he wanted to find out information about the mutual friend death. Again I confronted him and told him to stop talking to girls behind my back. He said it would stop but again I noticed he’s been on his phone a lot again I asked him if he was womanizer and man who need the attention of other women. He didn’t say anything but changed the subject that he was devoted to me and look what all the work his put into our relationship. And of course making ME feel bad. And again today while he was showing me something on his phone a message came through from another girl. What the fuck am I doing here why not be honest with me and us part way and he can be single obviously he want the single life. I don’t know what to do. I know I’m stupid for saying that.
