It makes sense that this is bothering you. Twenty-four or more past partners can sound like a lot, but what really matters is who your fiancé is today. People can change, and some people leave their past behind when they find someone they truly want to build a life with. Try not to compare yourself to people who are no longer part of his life.
The most important thing is trust. Ask yourself if he treats you with respect, keeps his promises, and makes you feel safe. If he is honest about his past and has shown that he is committed to you, that says more than the number of people he dated before. You should also be able to talk openly about health, loyalty, and your future together.
Don’t rush into marriage if you’re still feeling unsure. Take the time to have honest conversations and make sure you’re both on the same page. A happy marriage is built on trust, honesty, and teamwork—not just on what happened before you met.
