Search Results: feelings for the person you once loved

Let's assume, here, that it's a date, not a hookup. You're trying to get to know the person.
They're not freshly off a really bad breakup.
They're not angry and ranting.
You're not a rebound person to them.
A decent amount of time has passed since they've been in these relationships, so their emotions are not too heated, but they do have some feelings of love, pain, etc.

Now, do you want, or not want, to hear about their past relationships and people?
Does it make a difference whether it's the first date, or subsequent dates?
If you are answering yes, I assume you want to hear a bit about it, but not take up the whole date. That doesn't need to be specified.

There's no right or wrong answer here. I'm just curious, because I've heard people with strong opinions on this.

My opinion is that I want to know. It's interesting to me, and it's informative.
I would be worried, though, that if I ask, it could open up a whole can of worms, and the person might get in a certain mood, and/or it could be hard to get them off the topic, once started.
So then I have to think, is it worth the risk?
And in most cases, I would probably err on 'yes.' Except if the date was going really, really well, and we were both flirting and having a lot of fun with banter. Then I wouldn't want to talk about anything serious at all. I'd want to live in that moment, and stretch it out as long as possible, no distractions. But if the date was more serious, had more lulls in conversation, I would ask the question.

- We broke up a year ago and he contacted me 6 times to go out together, trying to reconcile. I ignored 5 times and went out with him once.

- Now, he's back and i am honestly quite moved because he kept trying. However, just yesterday, i found a screenshot of conversation (between him and a tinder girl). The conversation was a few months back.

- The girl asked if he wanted to fuck, nothing else no string attached. He said yes.

- I confronted him and he told me he dated this girl for a while but realised she was cheating on him so they broke up. And the conversation I saw was the conversation she wrote to him after they broke up. He said yes because he thought they could still get back together.

- Honestly, the feeling wasn't nice to find out but again, he was single at that point of time but its something i couldnt accept so i just told him straight up, i dont think i love you enough to accept this.

- He said he is willing to do anything for me, as long as i will be by his side because he really loves me and his family does too. He also said he will prove it to me that he's not such person and he will not do this again.

Should i trust him?
