Look OP there are loads and loads of women on this thread, with personal experience of this, pleae listen to them.
My ex was like this, I had a very active ex life before I met him, and he fucking hated it. (He'd had sex before me as well btw!)
I remember once sitting there open mouthed in complete bafflement/anger/shock as he went on and on at me about my past, about how it made him feel, about how he couldn't bear going out with me because everywhere we went I mught have slept with someone.
When I asked him what he expected me to do about, he wouldn't have an answer, he just wanted me to feel shit all the time, and it is a form of abuse and control.
If I spoke to any man at all, I'd be accused of having slept with him, so I stopped speaking to men, even my friends.
If I went out with friends he would go mental and accuse me of only going out so I could pull- just like before him- so I stopped going out with friends.
If I went out in revealing clothes he would go mental and accuse me of trying to attract attention, so I stopped wearing those clothes.
By the way, I'm not saying your's will do this, but this was all a prelude to going from control and guilting me, through full on emotional and financial abuse to finally physical violence when he didn't get his way.
It was a simply a great excuse to control my movements and have me treading on eggshells, I was a cowed and completely different person when I left him.
It is never acceptable, ever to make someone feel guilty about their past, or use it as emotional manipulation.
I wish someone had sat me down all those years ago and said "Look, it is not passionate, sexy or dramatic to be paranoid and controlling. It is not a sign that he cares deeply for you, it is a sign he thinks of you as property, and that you have already failed as his 'perfect woman'"
Being older and wiser, there is absolutely no way I would tolerate an even vaguely negative mention of my colourful past, don't like who I am?? Fuck. Off.
