Feeling lonely

I broke up with my boyfriend in October last year. I’ve been totally fine about a month later I downloaded tinder and bumble have been chatting to guys. I met one and have seen him a few times. But I haven’t seen him in a month. And now I just feel lonely, i was distracted and now I miss the feeling of having a boyfriend, a best friend someone to talk to and hang out with. I feel like everyone around me has a SO and I’m just left out. This guy I met was/is something casual and I think I’m catching some feelings but I don’t want him to think I am so I’ve kept my distance. But he hasn’t reached out but I’m not really sure if he’s a social media person because we only chat on Snapchat and I know this is stalkery but he’s snap score doesn’t go up at all so I know he’s not on it often.

What should I do?
