I may have found a mans

Ok so I'm 14 which is really young for this so I do need your opinion about this. So this guy this is and his 17 we play video games and stuff together and talk a lot. Last night when I was on the phone with him, we were talking about dating and stuff and my ex had come up since I just broke up with somebody. And he said he could help me forget about him if I become his girlfriend. I haven't said yes or no but I do want to say yes. But I'm scared if I do he's going to leave me and use me like everybody else has. So please help me with your opinion deep as brutally honest as you can🙏

I know school is really inportent and stuff but I want to experiment a bit. But not in any sexual way. My last guy tried to and it didn't end up so well for him (I punched him) I'm not ready for sex at all I know. But I'm only looking for a puppy love thing I guess Idk I do think I should wait
