Do you have any advice on how to approach one guy that I may be attracted to but had a bad experience with in my previous relationship?

I'm maybe attracted to one guy that I saw one time when I was at adult gaming in April on Thursday. I was playing a video game called just dance but didn't noctied until after he was right next to me. Then I did see the guy and did noicted the guy to me. I did try to say hello. I didn't get much chance since I went on holiday / vacation. Now that I'm back from holiday / vacation. Did say bye to that one guy. Did say bye back to me. I still wanted to talk to one guy more but didn't have much time since carpark in limited time spot. Last Thursday wasn't there this time and was trying to talk to different people. I had a bad experience with some previous relationships with some men. I know not all men are like that. Just some can be bad men but other men can be real good men. Do you have any advice on how to approach one guy that I may be attracted to but had a bad experience with in my previous relationship?
