Hi
I think that you were right to tell her about that man's messages.
If she won't believe you, well, that is her choice, but at least you tried.
Since you love her, it is not surprising that you are concerned about what this man is saying.
She should listen, because this is not good at all.
If she ignores or disbelieves you, then perhaps she would believe her friends.
She is sleeping with another man and calling you a liar.
In my opinion, it is time for you to move on.
I cannot tell you what to do, though.
You cannot really please her, because she has made the decision to leave you and to go to him; to disbelieve you and to believe him. She has made the choice ~ and it does not sound like a good one.
If she is with another man, she has no right to demand your affection.
At 21, she is still very young. She may not be ready, yet, for a serious commitment ~ especially as she moved in with you when she was even younger still.
I think that you are right to consider moving on. You should be with someone who will be a good partner to you ~ not someone who demands your attention while sleeping with another man ~ a man who sends disgusting texts about her.
She does need to learn the truth about him though. She is very young, & probably vulnerable, and he sounds lacking in respect ~ but I would let her friends tell her ~ the ones who already know and told you to contact her ~ you have already tried and she called you a liar.
I'm sorry to hear about all this & I hope that things work out well.
And please don't call yourself a loser ~ do try to be positive!
