Need Advice on a relationship with an Older Woman?

Sorry in advance for the long question. Hi, I'm in desperate need of some advice. I am a 26 year old man who has been dating a 36 year old woman for about 5 months.I am very concerned about the age difference and what that will mean for us down the road. Just last week we broke up and it has been killing me. I really like this girl and I want to be with her, but the age thing is just a 24/7 nagging issue in the back of my mind. We split up because she is wanting to be in a relationship with someone that will in a few years materialize into a family and having kids. I am terrified of this. I want a family and kids, but i'm 26 and thinking about that happening in the next couple of years scares the hell out of me. On the other hand, I really do not want to lose her, she is wonderful in every way, and though we are 10 years apart we are on most of the same playing fields, intellectually, physically, professionally, etc. I have been in only 3 relationships that have lasted more than a few months, and have dated many girls, and this is the first one that has ever meant something to me, the short of it is, I have fallen for her and I have been down and out since we split up. I need some objective advice. Do I try to get her back or do I just move on and accept that our age difference is just to much to overcome. Thanks in advance for the advice.Need Advice on a relationship with an Older Woman?
