Am I overanalyzing or in denial?

I need a third party perspective of people that I don't really know. I will write out the infractions against him that have occurred and then I need someone to tell me I am either over anaylzing or in denial. This is over a 5 year period and we have been married for 1.5 years.

1) I received an email (from an ex) stating he was hitting on her little sister publically over a social networking site and sending her emails. He was confronted, stated he was being friendly and I took her as a jealous ex at the time. She told me he was a cheater but refused to tell me any details so I didn't want to rely on gossip.

2) Then came Narelle- another woman on an email where I accidently found the email (didn't snoop) about him saying how hot she was and he wanted to talk to her. She confronted him via email about how he was seeing someone and was obviously creeped out.

3) Shortly before we got married, one of my closet friends calls me to tell me she needs to get something off her chest before she lets us get married. She stated that while I was pregnant with our first child that he was trying to sleep with his best friend. He was sending her texts about it and everything. My friend stated that his friend would admit it all. I confronted them both and they both denied it fully. I did however find out that he slept with half the girls he is friends with at this point, but it was prior to us....

at this point I was getting married in a week, just spent so much money and was stressed I chose to trust him despite my gut instinct but I have no valid proof.

4) He goes to FL with the guys for the superbowl and tells me there were no womanlly interactions, etc. I didn't know his ex lived like 5 minutes from there either, besides the point... So he comes home and is talking a few weeks laters and then accidentally mentions the strip club and the fact that some of the guys paid for sex at the hotel... but of course he didn't, right? BTW strip clubs don't bother me and he knows he could have been honest

5) We are at a party at his house and my friend at that time tells me that she found pictures of his manhood on her phone. It was true and he said he did it as a joke.... however he continued to drink and I found them in the bathroom together, her pushed up against him on the wall trying to whip her boobs out... didn't end well that night but stupid me I chalked it up to drinking and he said he was pushing her away.

6) We now how a joint phone bill which he pays and I never look at. Well he was online looking at it and we decided to see who texts more. We scroll to his area and I see three unknown numbers that he calls and texts a lot. He told me two were from girls he went to school with and one was this internet thing that keeps texting him and he texts back stop each time... However it was obvious it was not so I called it and low and behold it was another woman. He stated he didnt know why he lied and that she was going through a hard time and he knew her from middle school. He texted her from when he left the house to when he got home. He goes to darts one night a week and they texted every five minutes... you could see when I texted him and it was ignored... he always said he didn't have his phone on him... lies

7) last night, we went out with my friends drinking. He drank quite a bit. We get home and my best friend calls me upset because he grabbed her *** in an inappropriate manner and she felt uncomfortable. I said something to him and then he passed out on the bathroom floor.

Sadly I think there is more but my memory is failing right now... so tell me am I overanalyzing or in denial? Is he a cheater?
