It's not often like the movies.... when you see someone across the room, your eyes meet, and wham! Nope. That's ( usually) Hollywood. That does happen, but in my experience it usually fizzles.
It's tremendous pressure to put on a young lady- and yourself- to think hey, are you The One? My best friend, my lover, the Mom of my kids, the woman who'll stand by me if I get some horrible disease and am bedridden for the next 40 years?? LOL I said it before, relax. You can never ever judge a person like that until you add real love into the mix. People die... willingly and without thought ....DIE for others that they love. How can you see that before hand? You can't. But you can feel it for others.
Just start dating,. Yes, you are allowed to date more than one girl at a time.( As long as you never lie about it.) Just because you go out once doesn't mean you have to go out again, or again.
If you live in a small community never talk about ( in detail) what went wrong with another relationship until you are waaaaay into a relationship. Everyone deserves their privacy, even somebody who has wronged you. It is gentlemanly to never dis the the gal, no matter how badly she wronged you. The old expression "don't kiss and tell" still applies today. It applies not just to smooching but all 'personal' details.....romantic in nature or just personal stuff. You will quickly build yourself a rep as a class act.
I feel like you are skipping a couple steps before worrying about trust issues. The does-she-like-me-kinda-maybe? Step. The nervous stomach of asking her out cause you don't even know if you want to but she's cute. First date nerves.Do I want to kiss her goodnight? Should I ? No?Yes?No? Ask her out again or not? LOL the first several months of a new relationship can make your head spin. Enjoy
