Not sure what to do

I was with women for 9 years prior to my ex who was the first guy in 9 years. I was in a relationship with my ex from Jan of 2008 until October 2012. We have a daughter that is almost 33 months old. I am the one that ended it originally. We kinda hung out a little here and a little there and were still intimate for awhile on and off since We split in October. We have decided that it just isnt going to work. In September 2011 I found out he was talking to someone else. We decided to try to work it out and stayed together. I began sleeping with someone else that December. I basically just stayed with him for our daughter, and continued to fool myself for another year. Before I found out I was pregnant, I had though about leaving him. I am having a difficult time beginning to date though. I went on a couple dates with a guy I met on a dating Website. I thought I was capable of "dating". I however cannot grasp the idea of talking to multiple people at a time. I want to get to know 1 person and see where that goes. The guy I went on a date with however is only wanting casual dating, after he told me that he knew he could develop feelings for me and that I would be the perfect girlfriend. I am at a loss. I don't know why I am having a difficult time with the fact that this guy "isn't ready" for a relationship (using his 6yr sobriety from alcohol replaced by a sex addiction as his reason). Help... This is so difficult and I don't like this feeling.

Hello! I've never been in this type of situation, so I'm not sure how I would respond. Maybe you can take it one relationship at a time. If one guy says he isn't sure he wants a long-term relationship, then you can scratch him off your list and look for another guy. This current guy doesn't strike me as a good catch.

I hope this idea might help.

I would think of it kind of like an upside down pyramid :-) and go from forest to "the" tree? Dating is a way to get a group of more compatible "records" from out of the dating site and then you date each of these until you find one that is the most compatible to then research in depth? This guy, being the first sounds like a throw-away :-) Now you better know what you are looking for and what the guy probably doesn't look like in terms of background? You can more easily sort through other guys that may sound attractive on the site.

but how would you choose which one person? at random? the first responder? unless you at least talk, literally, to multiple people at a time, how will you select where to start in any way that is more or less meaningful?
