To quote the OP:
I'm dating a lovely man now, but I honestly just had this feeling like... It's inevitable, at some point, he's gonna be like all the rest. I can't trust him although he's not given me reason not to.
Sorry @AdamRyan pretty much everything you've posted for the last few pages (especially to @PartridgeInAChair) seems to contradict what the OP has written herself.
Here is a woman who has met a potentially decent man but due to previous experience has been burnt. At this point in time none of us can categorically say that this man is good or bad. FACT.
You can spin this however you like and reduce it as you have, but @PartridgeInAChair is 100% correct when she says she not defending men (none of us actually are - but you only want to read one thing) but simply saying there is some hope amidst the many men out there. Sorry but that's pretty irrefutable. Stats may say this or that but there is always hope.
I posted up my OH's experience with his ex. I'm actually a divorcee and my ex had an affair with my best mate who was married herself. Some mate. I can 100% relate to the quote that I pasted above. How couldn't you as it's so common. Yet both my OH and I somehow found it in ourselves to trust again. We could easily have been like the OP, sabotaged the relationship and gone our separate ways. Hell, he could've been dating the OP as a 100% decent bloke. But 25 years on and we're still happily married. This isn't being smug. It's one side of reality a reality some don't seem to like but there you go.
What I find interesting is that so many (and there are many) of the reductionist posters have married supposedly decent men themselves and have decent friends and family members but are so heavily arguing the case that "you just don't know because so many men are violent rapists and abusers". Like arming women with this obvious nugget of info is actually helpful. Yeah we all know this and there's not much we can do about this.
But the stark, unfortunate, reality is that none of us ever know and that is always the gamble we take. All the other heinous shit aside, it's a lottery and we can either go for it or not. Sadly, as with most of life, there are no guarantees but IME if you're in it, you have to give 100% or get out. That's the OP's dilemma and one she can only decide for herself.
All this back/forth between us posters is largely irrelevant as IME noone asking for advice ever listens. They want to hear opinions but rarely act untill they decide for themselves.
Anyway, last post here. All the best OP and I hope you find peace and success in any decisions you make. It's hard AF and I'm sorry but hope you find a good egg
