There are pro's and there are con's to dating a single mother. If you date a single mother, you always need to be on the lookout that she isn't someone that's using you to either play daddy or have you support her and the kids. Not to the point of being paranoid about it or automatically accusing her of it or not giving her the benefit of the doubt, but there are signs that she could be someone looking to freeload off of you, and you need to just pay attention for them. Stay open minded, but pay attention for them. This is not something that's gender specific, as there are plenty of single dads out there, looking to freeload of some kind-hearted woman. Remember, for every single mother, there's a single father somewhere. That can be you one day, after being married and having children, then splitting with your spouse.
I understand that sometimes, especially the younger the children are, it can be a real hassle. I've experienced it before. You're getting a little comfy on the couch, or maybe in the bedroom and the kid starts crying. Or the kid starts banging on the bedroom door. Or the kid just won't fall asleep at 11:00 or 12:00, when you wanna spend some alone time together. I understand how this can be a problem, I've been through it. It can be annoying or frustrating. I've went through this before. The two single mothers that I dated a bit, one was 42 and had a 17 and 12 year old at the time. Didn't really have any problems with the kids getting in the way. The other was 22 and had a daughter that was about 14-16 months old or something? Had a little bit of experiences that I referenced a couple sentences back. These were what I would consider women of quality. I certainly never felt used by them or that I had to compensate them financially for their children.
Bottom line, there's a lot of divorced people out there, or parents who are no longer with the mother/father of their child. It happens. There's a lot of quality people who fit this category. I know there's a lot of people here, who hold divorce (children or not) against some people. ''Well if they're divorced, it tells you they're not fit for a long term relationship''.
That's a whole other topic, though.
Oh, and don't hold it against him/her for saying ''My kids come first!''. They were there before you were....
