Can I Trust Her

I have met a lovely woman who was previously married.
She is 57 and I am 60. I have been seeing her for about two months, she has her own house.
A couple of times when I was there, a couple of guys called round at different times. she went outside and was talking to them.
When she came in after the last one called round, I asked her who they were.
She told me that they were guys that she was having regular sex with, but had told them it was over because she had met me.
I then as the question about how many lovers she had been with.
She then told me her total was 61 including me.
39 had been in the last three years, including a threesome with two 18 year olds.
She said that she didn’t stray when she was married and wouldn’t while we are together.
I think her total is a lot, but I don’t want to leave her??
We fucked on the first night.
What should I do!
