What do you think of dating a younger guy?

What does it mean when a guy doesn’t open up and talk on a deeper level but does with someone else. He kinda lies about certain things but with this other girl he used to tell her everything. I know this because I’ve seen their conversations and he spoke so freely and his life and feelings and said he wanted to be with her. Yet with me I don’t get that but he messages me all the time

Would you ever post your outfits? I can just tell you have a good sense of style

Me and this guy spoke for months and we had a genuine connection but nothing could happen. I’m struggling to fully get over him he’s different from every guy I’ve ever spoken to. I have our conversation saved right back from the time we first spoke. Should I delete it? I know it’s a daft question but I feel like that’s the only memory of him I always go back to it and re read it

Me and this guy talk now and again but we’ve never had each other on socials. I found him on insta a while ago and always checked his insta even though it’s on private. Anyway I checked today and he’s blocked me! Like why would he do that when we have never messaged each other on there or send request. He found my insta but never told me 😑
