Is there a time limit??

Is it normal to feel like this? My relationship has had a lot of ups and downs.. mostly downs.

Recently I’ve just been overthinking everything he’s done to hurt our relationship. These things have happened the earliest 5 months ago. I feel like I was in survival mode because we had so much going on and a baby on the way. Now that I’ve really just sat down with myself all those feelings have come rushing in and I’m not sure if I want to continue this relationship. Is that right even though we’ve “moved past” / swept everything under the rug? Am I allowed to be upset about things that have happened months-1year ago? We’re in a better place now but I’m still hurt and have little to no trust anymore.
