I have been with my boyfriend nearly 2 years.. we have 2 small kids together and have had our fair share of problems. He also has a drink/drug problem he is currently in help for. I have been made aware by him of a fantasy of him being with another man while he has been drunk but we have never discussed sober. (His idea not mine) a few days ago I found messages on his phone to other men talking dirty and sending dirty pictures.. what do I do.
