So, my SO has a place that he goes to quite frequently and has been spending more and more time there during friday nights mostly. He's there from 530 to midnight or later most nights and always just talks about hanging out with his guy friends. I found out there's also 4 females he's been hanging out with and one in particular he just doesn't want to talk about at all and got mad when questioned saying she was his secret lover. Idk what to do or how to react to this but this is where he is most weekends without me because I have my son, and I have a bad feeling that this one he's not wanting to tell me about is more than just a buddy of his.
