Dating Advice, please..

Recently, me & the father of my 3 kids broke up. It was a pretty nasty break up. But I know someday I want to get married. Heck, maybe have a couple more kids with that someone. But I know the first step is dating. I've never done this before. Me & the father of my children met when I was 13 (he was 15). That same year we decided to make us official. Now 9 years later, almost 10, I have to do it all over again.. (I'm 22) But I feel its harder for me because I have kids now. I wouldn't just be with anyone, because my kids are my 1st priority.

Does anyone have experience with this? I'd appreciate the advice.
