Is it realistic to hope to find love at 30?

30 M here, job holder. I was in a 4 year serious relationship, then found out she cheated on me and I broke up. I have been single since, it's been a little more than 1.5 years. I have been on my own, haven't been on any dates or even tried to get to know anyone. I wanted some time to heal and also work on myself.

I think I am ready to start seeing again, but I don't know where to look. I was thinking of trying dating apps but I don't know. Is it going to be any good? I don't care about someone's past, whether they have gone to many dates, as long as she knows how to stay good once you have found good.

Arrange marriage is not something I'm interested in. I cannot marry someone who doesn't love me, cause who's to say that she ever will?

The only two options I see on the horizon are dating apps and messaging random people on social media that are on my list. The latter is a bit awkward cause I have not done that since I was a stupid teen and I have also never been good at it.

Any advice?
