I personally went thru a similar experience right after 2020’s quarantine. I had too much time to think and became aware of all of my past traumas. I just wanted to be alone, needed time to process things and reevaluate every single thing in my life. Told my boyfriend I needed a break and he convinced me I didn’t have to do it. And he ended up being right, I would have lost the love of my life. Just know that you don’t have to go thru this alone, the best thing to do is going to therapy, and opening up about how you feel to the people closest to you. If you feel “off” towards love and your relationship it doesn’t mean he can’t be there for you and that it has to end, everyone goes thru ups and downs :)
