Is it weird to want to look for love online?

So I (19M) don't know if this is just me or not, but being an introvert, it helps making a easier connection with someone's personality vs going after looks in online dating. A lot of my HS Friends told me they started dating online, and a few of them have already found the person they have always wanted. For me personally, I'm not sure how I would go about online dating as some of them have been asking me to try.

For starters, about 8 months ago I got cheated on by my ex gf (18F) and I grew up surrounded by infidelity during my childhood and I just don't know how some people have all that trust in a LDR. I honestly haven't really wanted to get back into dating because my mindset is that if one girl did that, all the rest of them will. It's hard to find someone loyal in this generation.

The major reason why I think online dating would be more beneficial for me (by this I don't mean dating apps btw), is that I'm 6'4 or about 194 cm and there aren't a lot of taller girls in my area. I don't know how comfy I would be dating a shorter than average girl as I don't want to make them feel weird, even thought some of them have told me they'd find it adorable. (Anyone know why?????) Anyways, is it worth giving online dating a shot or should I just stick with irl people? Any feedback would be appreciated :)
