Curious question: how come people date someone new after their ex pasted away? Like Ariana’s ex Mac Miller died and now she’s with Dalton isn’t that disrespectful?

I just got broken up with 13 days ago after 5 months super unexpectedly for no reason other then he needs to work on himself. That night i was really alone because my parents told me he was a good influence on me and my friends weren’t so i had no one. I added this guy on Snapchat that same night and we’ve texted and called every night since. We met 3 days ago and it went really good. We were both nervous but both talked about the next one and how we both had fun. Last night he went to bed without even a goodnight or any talking that whole day but apologized and said goodmorning this morning. Then tonight he randomly sends a paragraph saying he doesn’t think it’s going to work. When i asked why he said “Idk our personalities are just a bit different and idk if I’m really ready to be in a relationship”. It makes sense i guess but I’m really struggling with the fact that my last relationship said that exact same thing and i can’t help but think there has to be something wrong with me. I never cheated or did anything that could’ve upset either of them. I’m 17 and i really feel like i should just stop trying for a relationship but no one is giving me any kind of advice so I’ve just been over thinking all of it. Any past relationship I’ve gotten over by meeting someone new but I don’t know how to “work on myself”. I really think I have a fear of being alone. Please help!

So me and my boyfriend of 5 months broke up and I'm very sad about it, but I'm trying to move on. But it seems like nobody wants me. They either ghost me or we hangout once THAN ghost me. I need someone to date.

Hey, my girlfriend recently broke up with me and immediately got with a guy she had told me not to worry about. For her side of things, she hadn’t admitted to herself that she had feelings for him but then started thinking she was polyamorous since she says she has feelings for both of us. Since I’m not poly, she decided it wasn’t fair to me if she had feelings for this guy. But it really hurts since 1. I have ROCD and was terrified this would happen 2. They were flirting in front of me the other day after she had assured me she didn’t have feelings for him and 3. They had agreed to date before we had broken up, even if they only made it official afterwards. I can’t help wondering if her feelings for me were all a lie until something better came along, and since this was my first relationship it feels like I’m unlovable. Even if she says she broke up with me because she’s questioning her identity, it still feels like I’m just a side character in the love story of someone else more important and worthwhile. My OCD has really latched onto it all because it feels proven right. Any advice?
