Advice

I started talking to this security guard at my job about 2 weeks ago. I’m almost 19 and he’s 22. He has 1 kid but he said his baby’s mom is pregnant but he dont think its his (which it most likely is). but he’s been stopping by my house late at night and we’d just sit outside and talk for a little bit. But recently we’d only talk for about 30 minutes to an hour before he has to go. He’s a sweet guy i haven’t really noticed any red flags but i feel like we’re not progressing. Sitting outside and talking is only fun for a few times not consecutively. He’s really not that good a making conversation and neither am i but i try. i like to go out but i dont want to push it on him. if he wanted to take me out or something, he would. The last time i saw him i suggested that we go to the park and we did. But i want to get to know him more i just dont know how i should go about that. Even though he asked for my number, im just afraid he doesn’t want to be seen with me or something because im taller than him.
