He's always happy to see me though and once their sister told him " you better stop talking to his girlfriend before he gets mad"
Tonight I shared something on Facebook saying "men only, give women dating advice" he commented and said, "let a real man love you". I said "welp, you don't have to tell me twice" (other guys commented as well). he literally replied saying "HMU and left his number"
I don't know what to do. I have the other brother and sister and law as friends. They might see it, as well as my boyfriend if he goes on Facebook.
