Just to say on messaging, I was serious about finding a DH and even put that in my bio, but, I was working 80hr weeks and would only reply on a set day.
DH's friends told him to ditch me as I didn't seem serious, but I hadn't told him about the work schedule as it was temporary and didn't want to scare him off by coming off as a workaholic/ having no work-life balance.
There's a middle ground and obviously, don't get stuck waiting for ages.
Also OP, it's a numbers game as others have said.
I used to swipe left based on trival stuff, for example an area where DH lived was not so great, but he'd bought there to get on the property ladder and we've since moved.
Look at it as an investment into your future and the more dates you go on, the closer you get to meeting your future DH.
It's a shame when they don't commit to a date, but keep swiping.
Don't waste time on the phone either, I clicked with two but the actual dates were not great.
Unless obviously incompatible, I went on two dates each, allowing for first date nerves.
The other thing is people don't mention they met their partners on Tinder due to the hook up thing, so you'll be surprised how successful it actually is.
