Girls, why are so many women these days so scared of relationships?

I go on dates with women and everything is going well, chemistry is there, values are there, attraction is there, then things get serious, then they freak out and get scared and push away completely. It's actually really annoying. I have friends who have had the same experience so it's not just a me problem.

If this is the case and women are so scared of comittment, how can we fix it quickly so that people can start to have healthy relationships again?

To clarify, because commentors have assumed that I only want to get into their pants. This is incorrect. I go on dates with them for a couple months, then I ask them to go into a relationship if I feel the time is right. Nothing nefarious. Usually the women get freaked out and scared when I ask them to go exclusive or even after two months of just going on dates. How I know that they get freaked out or scared is because I find out at a later point that they have trauma that makes them scared.
