Husband talks to other women.

So for the past couple of months my husband has been talking to other women. Every now and then I would see he gets a text message of a woman either naked or posing some sexual way. He would ask them to show him their ass or vagina. He would call them 'babe' or 'sexy'. Once I even saw he received a message saying 'I love you. Don't work too hard'. Plus he's into Spanish music now a days and most of the woman he talk to are Spanish. I really don't know what I should do or I'm doing something wrong. Every time I would ask him about it he ignores it and somehow blames me for everything that is happening.
