I have been with my girlfriend for a while now and I have been planning on asking her to marry me by the end of the year. her family loves me and my family loves her everything is great I know I have found the one and I know she feels the same way and everything is great but one thing and that is what I need help on.. Her ex she only dated him for 7 months and he cheated on her with one of her friends and then she started dating me a month later and he tried to do whatever he could to get her back and she told him to go to hell and I did not get in to that I let her deal with it I was just here for her because we all have a crazy ex but then he sent her something again then came by her work and he put her down and made her feel bad for not being together anymore and it made me really mad and I said I would end him from talking to her and she said no she could handle it so I let her do whatever and she told him off again so now its been a few months and he texted her again and started putting her down again and just saying all kinds of stuff to her and she blocked his number at least that's what she told me we are always together and she tells me everything and shows me everything but I would to go by his work and tell him to leave her alone or I will end it forsure but I don't want to do that and she gets mad at me but I really don't know what to do its driving me crazy and its going to hurt our relationship and I don't want to ever lose this girl I mean I want to marry her.. so what should I do go talk with him about this or just sit back and let her deal with it?
