I kind of dealt with this when I dated and married my husband. Luckily, HE never put the baby mama ahead of me, but she pulled crap all the time. Passive aggressively, so it looked innocent, but like Vee, I was thinking "I see you, bitch"
She ran around on him while they were together, and they split shortly after their daughter was born. I came along 6 months later. Well, we were friends for a year before, but didn't date for a while after he split with her. First few years were of her hating me, just because, and I can get that. Then we actually all got along for years and had a wonderful blended family going on.
Fast forward to the last few years: Baby mama got messed up on adderall, oxy, xanax and drinking. Also developed a hefty gambling addiction. Snorted and gambled her house, job and kid away. Kiddo moved in with us, and all hell broke loose. All of a sudden I was the problem in her life, everything was MY fault. She ended up proving that she always blamed me for taking him from her, now her child, etc. Turns out, my husband was "the one that got away" to her, and she had hated me the whole time. I'm leaving tons out, because it was so soap opera/reality show like that I can't even explain it.
Long and short, Kail is so much like this woman it is eerie. I see the future, and it isn't pretty. She played nice with Vee, but she always secretly blames her for Jo not coming back. She will always hold Vee at fault for her "perfect family" not happening. All I did was fall in love with my husband, who was not with the mother of his child, but now, 22 years later, it is still all my fault. They were never married, but she has used my hub's name on documents and introduced herself as his first wife. She blames me for none of her plans working out, and Kail seems to be mirroring the early behavior I put up with in this relationship. It killed her that I got the name and the ring for some reason. She didn't "win" and it is all about who wins and who has the most at the end of the game for her, and that's how Kail seems to me. She always wants to win, and she will win in the money and more kids dept, but it won't be enough. Jo will be the one who got away, because at the end of the day, he left her, she didn't leave him, and it will eat her up. Like in my case. I can't put it into words, but I promise I mean well here lol
Jo is playing with fire by almost but not quite flirting with Kail. I don't know what his motive is, but he's toeing a fine line and needs to be careful. I just think this whole situation is going to be even more messy before it's said and done. And if my husband EVER talked to his ex about me like Jo did, throwing Vee under the bus, I wouldn't trust him at all. That is so wrong of him.
