I’m (F25) trying to be emotionally strong in times of uncertainty, trying to improve – To stay loyal or to move on from (M35)?

Hello, I really hope you’re all doing well! I’ve known someone (they’re a really sweet person, this was my fault) almost for 2 years but we got closer nearly a year ago. It’s my first time experiencing something like this. Around early December gone, they weren’t texting as much (we didn’t text everyday but the days of no contact increased to 5 which was unusual, the longest since has been maybe 9 days and I’m the one left on read) so I thought they lost interest. I would ask if they still were interested but the lack of contact continued so in the heat of anxiety, broke things off but said sorry a lot and made sure everything was okay. They were on holiday but had no idea, was worried because thought we were going to meet up once around that time.

Multiple days of no contact continued (thought I messed up and caused bother, would apologise and ask if we were okay), we did end up talking about what happened and turned out they were okay with everything. They haven’t been well so I would reach back out to see if they were doing well but they like to be alone, feel really bad about disturbing them and have been overbearing. Have initiated meeting up sometime in the future (when they are better or help distract them), they say to look after myself (which I took as a no but turns out it wasn’t, I’ve been trying to get better for years now) and the whole thing I got wrong. I’ve been very selfish.

I’ve been detaching myself but I’m a bit too loyal and would love to wait and see if they would like to continue after they get/feel better or should I move on? It’s the least of their worries, I understand that and trying to see what would be best for both of us ❤️

TLDR; Known each other for almost 2 years, got close almost a year ago but days of no contact increased so thought they lost interest. Turns out I was wrong but days of no contact continued and got longer (up to 9 days without getting in touch), they haven’t been well this year and would ask how they’re doing but they don’t like the fuss (I’ve been overbearing and selfish.) Tried initiating to meet up when they’re better but it feels different, it’s not like how it used to be. Been told to look after myself (have been trying to get better for years, even before we met) after initating which I took as a no but that was a mistake. Would love to stay loyal but wondering if it’s best to move on, have been detaching. They’re a sweet person ❤️
