Stalkerish ex gf

Now I know us as women can be crazy at least I know I can be lol. Sure I’ve been obsessive over and ex or someone I was falling hard for but he didn’t feel the same in return but at some point you got to draw the line and be like hey, I have I taken this too far? I don’t have many friends or people I can turn to and the ones that I do, they just don’t know either.

Me and my boyfriend have been together for 10 months. He’s great, everything is great. He is everything I’ve ever wanted and deserved and more. Well his ex girlfriend always pops up randomly. One day she’ll message him. He tells me about and he just blocks her. Then she’ll make another profile and does the same. She will make Facebook pages after Facebook pages. I’d say she has about 13-15 pages. Most of them old and new as recent as yesterday. She added him yesterday and of course he blocked her. I’ve tried to message her but she blocks me before I even have the chance. Randomly she will even call me on messenger, video chat at that. Just a few days ago she sent me a friend request and then canceled it. It’s been over a year since they broke up and they weren’t together very long. She moved on and even got pregnant and from what I’ve gathered they broke up and she lost the baby. But during that time that’s when she became obsessive and hadn’t stopped. I don’t feel like anything is going on but it does give me anxiety. I don’t want to stress out over but it’s like why? I just don’t understand her way of thinking. It’s been awhile and he isn’t even her recent ex. I’m sorry for the long rant/vent. I just needed to get it out and get y’alls perspective. Thank you 😞
