Baby Mama's

Whatever you wanna call the other person lol.

So I just have to vent. My fiance has a daughter with another woman. Her birthday is December 2nd. Last year his best friend was able to take us 5 months out the year to see her, we live in Ohio and his daughter and her mom in Indiana. Same place his best friend lives. So we got to see her a few times each month, unfortunately for us we don't own a car yet so we can't up and drive an hour a way so he can visit her. Same time last year we had a small birthday party for his daughter, I was pregnant and so was his best friends wife. Some more back info his ex would flirt constantly and always sit by him even if he was sitting by me....It was WEIRD. She would try getting him alone too. So I was very VERY touchy when we went on these visits. I always got paranoid or felt I had to 10x up her. So jump ahead after we had our son and his friends had their son get togethers stopped. We became busy. His baby mama is crazy for one but she threatened him time after time about seeing his daughter last year, and after having our son got jealous and would text him still out the blue and tell him off the wall stuff. She text today inviting him to his daughters birthday unfortunately he has to work so we plan on going two weeks after which is horrible but finances are tight.

I just still feel this anxiety and like I need to buy a new outfit, dye my hair and do my nails sort of thing to up this woman.....does anyone else struggle with this? It's so childish, even her being ugly doesn't make me feel good. Now I will say her and I talk and get along but when I'm physically around her or know I'm going to be I always feel this way. Please advice from anyone?? I hate feeling like this.
