Affiliate Marketing Secrets

Have been with my fiancee for 6 months engaged 2 but we have got 10 yrs of history! What I’m wanting advice about is the other day a facebook notification popped on my phone saying a girl liked one of my pics of my fiance! I didn’t pay it no mind until I went into it she took his pic off mine put it on hers as mobile uploads titled you are sexy as ****! I told her that was disrespectful since me and him was happy together! She got all pissy about it saying he was hers first so I comfronted him about it he said he lived with her and her ex boyfriend but never affiliated with her! I said ok well u need to tell her to stop well he come back with u need to quit being so jealous and said we needed time apart! I broke into tears and hurt bc he is the only man I wanna be with for the rest of my life! Well he agreed to tell her to stop but the next morning I seen his phone and from that girl it said hey baby! He said he told her to quit talking to him and I seen the messages that he sent her should I be worried or is it her just trying to be a homewrecker!
