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?

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?

If anyone can maybe relate or offer advice if this is a normal thought process…trigger warning, I discuss breakups in this post. My boyfriend and i have been together for 3+ years. Over a month ago, we got into the worst fight possible where we actually broke up for a week. During the week I felt we were broken up but had the hope we were going to work things out - and then I come to find out he didn’t think we were broken up but just taking time apart. Anyways, I went to a party with my friend and my boyfriend and I’s mutual friends. Keep in mind, during this entire time I didn’t know if we were getting back together and for the first time in our relationship I had true doubts. Anyways, one of their friends I hadn’t met before walked in and I met him and thought he was cute. No big deal right? But then I remember having a thought of “maybe this was supposed to happen, you meet someone else and this is the universe telling you that”. I kind of remember brushing the thought off and I barely spoke to that guy the entire night/didn’t even have interest in chatting with him. Honestly didn’t even bother me. Now over a month later, I’m worried about this thought and feel GUILTY over it. Like, is that a normal thought to have while going through a potential breakup? Does that make me a bad partner? (Because now things are back to being great with my boyfriend). Dare I say it makes me feel like I cheated somehow, when literally it was just a thought. If anyone maybe can offer insight I’d so appreciate it. I feel like that was a normal thought to have given the circumstances but idk.
