Whoa whoa whoa girl.......you're trying to rush to the end of the story! You shouldn't be looking to enter a serious relationship. For Pete's sake you barely could have dated before you met your ex. Your goal right now should be to simply date. Shop around. Don't buy the first guy who comes along.
Sure, it's great to have a serious relationship as your long term goal. Just don't try to rush it.
I'd had a lot more dating experience before I met my ex. Still, after he left, it took me dating several different men before I got to the point that I was ready for a long term relationship. More importantly, I learned valuable things from each of those men, and it was because of those men that I was able to recognize the value in my current man.
Don't get ahead of yourself. Date and have fun. Learn a few things about yourself.
