My man is the best

Baby mama(she is married btw) decided to post pictures of my SO and her back when they were together and tag him in it with the caption "we were cute together" right after adding me. He instantly texted her telling her to take it down because they are not together and dont need pictures up on social media that look like they are and that he is with me. I didnt even say anything about the picture when i saw it he did that all on his own. Im sure that was her way of trying to make me jealous but i have no reason to be. I have a man that i trust and makes sure that i feel secure in our relationship.
