Dating apps

What is your opinion or what are your experiences with dating apps? I've never been into dating apps until a year ago when I wanted to give it a try and it wasn't bad, but it wasn't good. I've talked with 2 people from the app and the first guy that I spoke with already had a thing with another woman I just didn't know until after he ghosted me. After him a few weeks passed and I gave another guy a chance to know me and consider a relationship but as always, I like to take my time getting to know someone before making things official. Throughout the first and second month of talking everything went great until it didn't and I had to leave him because I found him back on the dating app, I only re downloaded the app because my intuition told me to and I was so heartbroken that I just wanted to leave him instead of talking to him about it and maybe I'm done with lies and excuses and that is maybe the reason why at first I did not want to bring up the fact that I saw him back active on the dating app. A month has passed since I left him and not once has he messaged me to admit what he did or to apologize or anything but that's how he is, he isn't the type to ask me if everything was alright or if I was upset or anything like that and that was the one thing that I didn't like about him. I've always been the one to always communicate about how I feel but at that time I wanted to see if he would notice and communicate with me and he didn't. After one month passed, I sent him a text because I'm ready to tell him the real reason why I left him and at this point he had blocked me on TikTok and unfollowed me on Instagram and he took a few days to reply back and all he asked was if everything was okay and I told him that I'm ready to talk and say the truth to clear this situation out and he hasn't replied since then and it's been days. I did write my first blog on here saying how depressed I felt but now I feel a bit better, I felt hesitant at first when I sent him the message but I feel good that I made the first step to try and talk to him again about this whole thing and even though he hasn't replied back I feel like it was worth a shot but now I have to move on if he has. People say that dating apps isn't where you need to go to find a partner, but I think it's a good option for people who do not go out to meet people.
