I def. don't put all or even most of the blame on Kail...don't get me wrong, she def. has a lot of emotional baggage and certainly has things to work on, however Javi also has some issues. Remember how clingy and passive aggressive he is? We really haven't seen that on this season, because he's not there, but he def. had/has a lot of insecurities and didn't deal with them well. I think Kail felt suffocated. He also admitted to being pretty awful to/around Kail when she lost the baby...remember him saying he blamed her for it? In his defense, he also said that he knew in his brain that it wasn't her fault, but that was how he felt etc. I like Javi A LOT and think he's a good dad and was awesome with Issac (hopefully still will be), but he also played a large role in the relationship and the issues of it. At the end of the day, I think it ended up being the fact that Kail didn't want to have anymore kids (totally her right) and wanted to make something of her professional life and Javi did want more kids and said that he'd resent her if they didn't have more. -He didn't say it in a mean way, but was just being honest with her. In the end, I think they just wanted different things, and while that's sad and ridiculously heart-breaking to watch Issac, I don't think it was about 1 person not getting their crap together or being selfish.
