My boyfriend created a insta account I didn't know of and ontop of that blocked me on it so I would have never found out or seen the profile, then I saw multiple messages of him complimenting and flirting with girls about they body, he was the one initiating the msgs as I saw him message so many girls at the same time, I was so shocked because he isn't the type to do this, he always talks about marriage and our future, and he was crying and apologized saying he was stupid and never wants to lose me and that I can go though his phone any time to build trust, I don't know how to feel because I have been so loyal to him, and Ig I didn't catch him it probably wouldn't have stopped, he wants me to give him a chance should I?
