My boyfriend has a baby mama who is legally married to another man, they talk everyday. What do they talk about, the intimacy is too much, they do say I love you at the end of every conversation. I confronted him and asked him if they are dating and he denied it giving me a filty excuse that he’s doing all that because of his son so that he will not be denied access to him. I still don’t believe all that because the way he speaks to her is different from the way he speaks to me. What should I do or is it my insecurities.
