Hi and let me too say I am sorry this keeps happening to you. I am a practical person and so bear with me because I am going to give you some practical advice.

1. Make a list of everything that bothered you about your ex husband. From pitching his socks on the floor to slurps his soup...
2. Write down things you don't necessarily like but could live with.
3. Now move onto yourself..pros and cons..be honest.
4. Never get really personal on a first date. He doesn't need to know why your ex is an ex. If he asks, he is fishing and it's none of his business. The first few dates should be light and fun..getting to see if personalities are compatible if you have things in common not whether you want children and if you make more than he does.

That should help you narrow down what you are looking for and what you can and are prepared to live with. I am not saying to start a date with 20 questions but it can help when your reading profiles. It also sounds like your a really nice person and that you may be trying too hard. Some men may mistake this for someone who is desperate for a relationship..any relationship and that's enough to not stick around for a second date.

And lastly...good luck. He is out there. My sister was married to a man for a long time. They divorced and she was separated for 13 yrs. She met a guy, didn't think he was the one but they ended up married and he is the love of her life and they have an amazing relationship. She met him through an online dating service. You might also want to branch out who says you have to stick with just one right!!
