I am truly sorry you've experienced this. But you need to learn to accept the fact that dating is a journey, a process, not an event. One month does not a relationship make. It appears that things were moving too quickly. You should not be involved with a dating partners children within the first month or even first few months.

I take a tough love position when it comes to men and women who allow themselves to become too deeply invested in a new dating partner so early on. In the very beginning, it is important to manage your emotions and expectations with a new dating partner.

The truth is that you are still very young and you were dating a woman who had a tons on her plate. In addition, you do not have the life experience yet to be able to manage a complicated dating scenario such as this one.

In the future, look for dating partners who don't have so much to carry. You want your dating experiences to be light, fun, unencumbered, not bogged down in drama, scheduling difficulties because of a dating partner's children, etc.. And, avoid dating people who have recently come out of another relationship.

Furthermore, it is very common for women who were with abusive partners to return to them after breaking up. It is a sign of significant issues that that woman has to deal with that would certainly burden your relationship with her.

My point is, you dodged a bullet here. Take solace in knowing that this relationship would have been fraught with difficulty and turmoil.
