I’d echo what a few people have said and go into it with relatively low expectations. I base this on my own experience though so take what I say with an inference of bitterness
My first furore onto a dating app was Tinder, after much pressure from my friends. The first guy I went on a date with after a few weeks on the app seemed absolutely perfect. He was a Doctor, really attractive, own home, own car, amazing personality, my age, no kids. He couldn’t have ticked any more boxes if he’d tried. Our first date was amazing and I remember thinking I couldn’t believe my luck that the first guy I’d met was like this.
We went on 3 dates in rapid succession and me, naively thinking he wanted the same things I did, slept with him after date #3. He stayed over at mine that night, left in the morning saying we’d make plans for that coming weekend and I effectively never heard from him again. It was an awful experience and it left me for a long time questioning myself, wondering what I’d done wrong and feeling completely used and pretty stupid. That put me off apps for a very long time and taught me a lesson about getting too into someone too quickly. I’m much more cautious now, probably too cautious really
Just so this isn’t a completely negative post though, I have met some lovely guys through Hinge and I do know people who have met their long term partners and even husbands on apps so they aren’t all bad, it’s just a case of wading through the dross in some instances I think
