My(24M) girlfriend (23F) wants me to stop talking to my ex (25F) after she said things about my dicks size

My ex (25F) was an ex for a few months but we are still good friends and pretty well in touch.<br><br>My gf (23F) doesn’t like the idea of this, we had a few fights but most of the time she’s fine with it.<br><br>Tonight she asked me to stop talking to her because I want her to feel safe in the relationship etc.<br><br>I said yeah sure, but I’m still gonna stay in contact with her for another week to let her know that I don’t talk to her anymore.<br><br>Gf snapped and said I’m annoying and she needs to hear the truth from my ex.<br><br>She texted her to say that I don’t talk to her anymore and to stop talking to me, my ex laughed and asked her why she needs to control me so much and that I get to choose who I talk to, not her.<br><br>Gf texted her later on again and asked her to stop talking to me or else, the else was a??. After that my ex picked a fight with her and said something about my dick size being small, I know her well enough to know that she was just saying it to annoy her.<br><br>I don’t know what to do now, my gf is p**sed and she wants me to stop talking to her, I don’t care if she says stuff about my dick size, she’s not the first one, I don’t have the biggest down there but I don’t give a f**k, I’m not going to let my ex ruin the relationship between me and my gf.<br><br>Gf said that she’s going to her brothers house now and that she’s too angry to talk to me right now.<br><br>I don’t know what to do, I feel like I’m being cornered to a spot where I need to stop talking to my ex and I don’t want to lose her.<br><br>What should I do?<br><br>Tl:dr; my gf want me to stop talking to my ex, my ex picked a fight with her out of anger<br><br>Edit: I have to say, there are a few types ofikk here that make me laugh, people who say it’s my fault because I’m allowing it in the first place, ok buddy, by that logic it was my fault that I got robbed at gun point when I was a teenager, the logic some people have on this website are insane.<br><br>The people who say I should stop talking to my gf because she’s controlling, I don’t even know what to say to you, I’m just going to say that you sound stupid.<br><br>Some people said I should’ve let my ex know beforehand, this was my bad, I should’ve handled it better, but I didn’t think that she would pick a fight with my girl.<br><br>Some said I got a small dick, sure bro I believe you, but you can’t change your genetics.<br><br>To the people who gave me advice on how to handle it properly, I appreciate that, I will definitely talk to my gf about it tomorrow.
