Is this cheating or not?

[Mainsode21]

Bit of background
Me and my boyfriend got together about 3 years ago we met through mutual friends and at the time I wasn’t really ready for a relationship but he pursued and I started to like him.
At first he helped look after my daughter ( from a previous relationship) while I worked and I wouldn’t give us a title ( boyfriend/ girlfriend) we went out like clubs/drinking and went to our mutual friends wedding.
After a few months I found out during this time he had got drunk and slept with a girl he had met a few times while me and him were in the talking stage.
I got angry and we didn’t speak for a few weeks but then I gave in and we started going out properly. I guess I started to see I had grown feelings as hurt he had slept with another woman while pursuing me.
I then found out he got another woman pregnant but this was months before I knew him so not really a problem.
Fast forward to now and we have one daughter together he’s a great partner and we have our nights out and time together. I can’t get that girl he slept with out of my head though. I think I was too forgiving.
I also found out he had done a few sexual things with another woman that I know of ( the mutual friends we have) but again this was before we were official.

Am I being stupid? Should I just forget these past hiccups and carry on?

He sounds like a prince among men.

He was looking after your kid when you hardly knew each other (in between going clubbing and sleeping with other people) but he couldn’t get his head around the idea that he had impregnated another woman so decided not to bother seeing his biological child for a year.

He sounds like a catch.

Excuse me while I point out your contradiction @yellowallpaper

”you can only judge him on how he is now.”

But...

“He's got form so it's always a possibility.”

A man like this wouldn't even make it past the small talk stage for me.

My thoughts exactly.

I honestly think funding or something should be put into educating people on valuing themselves and teaching them about appropriate boundaries etc.

He hasn't put a foot wrong since you became an official couple.

....followed by....

Yes, he wasn't the most responsible person in the run up and even a bit of a shit around his daughter

I mean, read what you wrote yourself?!

Your post is littered with massive contradictions - 'being a bit of a shit' around your own daughter is not just 'putting your foot wrong', it's a profound under-statement.

I honestly think funding or something should be put into educating people on valuing themselves and teaching them about appropriate boundaries etc.

Yes ^^

yellowallpaper abandoning your child for a year isn't a "mistake" so don't downplay it as one. It's disgusting.

My father behaved like that when I was a child and I am NC with him as an adult. Can't stand the man. Absolutely baffles me how women can have such low standards that they would want to be with such a man.

Having read all your updates, OP, I am more and more puzzled as to why his propensity for cheating (or otherwise) is your only thought in this sorry situation.

Putting everything else to one side I think you are probably feeling like this because as you say the sex has slowed down. Sex often slows down in most relationships but hopefully love grows. However you are interpreting this as a sign of him losing interest and about to cheat because of his previous behaviour. You could probably ignore his past when you felt all desirable and pursued but now that the excitement has gone you are worrying. You not bringing it up previously with him about his behaviour (which wasn't cheating) prior to you becoming official isn't more likely to mean he will cheat on you now, if he is going to cheat he will. For your own sanity I think you need to decide to trust him and stop thinking about the past, it doesn't seem that anything in his current behaviour is making you think he is cheating or about to cheat on you apart from less sex with you.
