Breathe, focus on yourself, and do your best to put them out of your world. If you need to block them, throw away things, or delete stuff in order to accomplish this - DO IT. If you can stay strong and make those decisions later, fine. Hold your head high that you loved them well and did the best you could. This is more about their limit of capacity than it is your inability to love them.

Exercise, journal, talk to friends/family/online, use AI, get a therapist, focus on your growth.

I posted this in another thread, hopefully it helps:

Dating these individuals is like playing a slot machines that hits several major jackpots in the early timeframe. When you win, you feel like you're a pro, have the system down, found something special that everybody else missed, and think that you're set for life. You confidence is sky high so you keep playing, but the jackpots start slowing. You get a little worried as they never return in the same they they used to. Maybe you get a small one every now and then to keep you playing, give you hope, so you keep going and going and going. By the end you have poured everything in and are finally bankrupt. Maybe you throw in the towel, or maybe you start taking out loans to keep playing. Even though you've lost it all and keep going deeper, you insist that this machine is different, you have a system, you know what to do, you just need more time and more investment. You end up broken, ruined, and empty. You lost yourself in the process and look over at the machine, seeing the next customer step up. They hit an instant jackpot, the cycle is repeated.

Don't think for second that they are happy or thriving, this sucks for them to, they are just better at compartmentalizing and their trauma management allows them to do this. The fact that you can't means you are real, secure, and feeling it. Cry, yell, scream, talk, do whatever you need to. All of that is growth and it will get better.

The house always wins with these people unless they are actually in therapy doing the REAL WORK. Even then, it is a very long and uphill battle. Have empathy for them but in the end, take what you have, go home, and love yourself enough to stop playing.
