What to do

Tatiyana

So last year I found my bf and his coworker/friend talking inappropriate to each other after she’s been all friendly in my face, he says he cut her off after we had so many discussions and arguments regarding her. This morning I found a text thread between the two and he’s just sending screenshots of our convo to her and saying “see what I have to deal with.” Knowing I do not like her for a reason and knowing what I saw and read between them. Oh he always deleted there text between each other too saying it’s so I don’t get mad.
