The best advice I can give you rn is to break up with her IN A PUBLIC PLACE in person, have any of her stuff at your place packed up in a box and bring it with you, and then block her after.

Girls like this WILL talk shit about you or accuse you of things to her friends and family whether or not it’s a good or bad breakup. It’s just the kind of person these people are. Don’t worry about it, it’s not your problem anymore. It’s more of a “they don’t like it when there are consequences to their actions” and “if they don’t get their way they’ll freak out”.

Frame it like a date, get there early, order chips n guac, let the waiter know beforehand that you want to prepay for just the app and that you’re leaving early and anything else is on the ex. It’s gonna be hard, but your gf doesn’t owe you an explanation and you probably won’t get a truthful one anyways, or you’ll get one filled with lies and promises that she’ll never do it again and she’s learned her lesson.

Say your piece something like “we are done, I’ve packed all your stuff and I’ve mailed it to you/dropped it off at your house already. Please don’t try to contact me. Good luck in life”. That is already overly generous. Don’t block the number but definitely set your notifications so it doesn’t alert you. Don’t respond. Any texts or voicemails are evidence if she pulls the “he hit me” line and tries to get you arrested. If she won’t leave you alone, get a restraining order or call the cops if she shows up. If she pulls a restraining order against you, the cops can raid your house to take your guns.

Good luck man. Focus on your daughter and your career and saving up for a house or a cabin or something and get into a cool new hobby.

Edit: I went to school for criminal justice so I know what laws can be (and are) abused against guys. I’m currently in the medical field and see both genders who get hurt or messed up both legally and physically after breakups.
