Search Results: how do i get my ex to leave his girlfriend

Ok so let me explain so nobody gets confused. My friend reached out to my child's father ex girlfriend going on rants because she's convinced she's a sneaky bitch not over him and that they might still talk to each other on the low and this is the end result.

His ex girlfriend wrote to him about me:

Joshua you need to control you girl and her sidekick forreal. Me and you aren’t talking nothing we both moved on and I can’t understand why they can’t. I’m very annoyed and going through my own shit like if you have to keep talking bad about me to make her feel good about her self keep doing it please, maybe she’ll eventually back off. If you gotta drag my name through the dirt go head. Like I’m tired of this immature back and forth shit. We haven’t talked since my daughter has been born so tell them to leave my family alone, period.

My child's father reply to his ex girlfriend:

Im sorry to hear that but like I told every one else I can barely get in contact with her half of the time she blocks me and than unblocks me but I never talked bad about you or anyone else for that matter

We live together with my boyfriend before but he ended up leaving me for another woman. He left and started to live with this other girl. I know why he left because I don’t have much money to support him. He said he needs to be practical that is why he is choosing this other girl. I, him and my family had a terrible fight because of the motorbike that my family steal from him because it was under my name but it was him who really paid for it.

I love my boyfriend so much even if my family don’t like him. I fought him so hard because I taught the future I see us together is real but not. My boyfriend said to stop bothering him with the other girl and he said he never really love me. He already get what he wants in a girlfriend. I am not his property and I can’t force him to love me.

It made me cry a lot. He never taught I only keep the money of the motorbike I sell it in a cheaper price of 42K. I am struggling financially because of the loan I never paid when we were still together and and lost money to help him before. That’s how I love him so much. I never spend it.

however I encounter this other woman, she seem to be boastful of her things and even money. But actually she is not really that type of girl who is very rich. she insulted me a lot and actually both of them with my boyfriend even if I really did anything wrong.
But I know my boyfriend is only after for money to her and I know he will also leave her after she becomes broke.

my question is should I return the money to my boyfriend, yes or no?
