How to do the dating app thing

My 4 yr relationship ended earlier this year. I just started using dating apps to meet new guys. But I feel like it’s been difficult to get to know anyone.

Whenever I match with guys and I normally ask to talk over Snapchat, but the guys don’t keep the conversation going.

I would like to eventually go on a date with a nice cute guy, but none of them keep the convo going.

Especially the one that I really like.

I know we are all adults and life is busy, but I would like to get to know someone and maybe get into another relationship

Any advice??
