Very few....
I am in a situation quite similar to yours where at this point I have lost all trust in men.
The last straw was the fact that I knew someone for years who I considered a great friend and who presented himself as a nice guy. We started dated a few months ago and it turns out he is an abuser behind closed doors masking as a nice guy in real life. Did this to me but I also found out he did the same to a previous girlfriend, to the point where she almost took her life.
I also grew up with an abusive father, was molested at school by two teenage boys and on it goes...
I met a couple of genuinely decent men at work or as friends and they are great family men who are incredibly supportive of their partners but I truly believe they are the minority.
The majority of men I have met have deep down been selfish, dismissive and too many have been abusive. If you do online dating again too many men on there are sexual pests/perverts, cheats and complete liars.
I think we still live in a society where women are seen as less than men and where our bodies are seen as commodities. As long as that continues, too many men will continue to treat women poorly.
I know women are not perfect either but I do thing we have a massive issue as to how men view women and what they think is acceptable.
At my age , late 40s, I have pretty much given up on ever finding a decent relationship.
