Help a single girl out!!

Sh

Okay so I'm now single after being in bed relationship for 7 years but I dont know how to be single! When do you start 'getting back out there' what does it mean if you and someone else are texting? I ask because someone is texting me, I do kinda like him but I don't know if it's just friends, he actually likes me too or he just wants to get it to my pants 😂 we have kissed once before... Ive told him im newly single (3 months) and that i have a son and he can't see me with anyone else yet but he's still texting! What does this mean!? Educate me please 😭😂
