Need advice on trust issues and how to get past them

Sierra

I’ve been with my boyfriend for five years. We’ve had our ups and downs (like every relationship). He’s broken my trust and we’ve talked about it and tried to find solutions, but I’ve been struggling. To be honest he’s been doing a lot better and has made serious improvements the last few months, but I’ve been struggling on moving past our past. I want to be able to trust him and I’ve tried pushing out the “what if” thoughts that creep into my head, but it seems like the more I push them out the stronger they push their way back in. Things will be fine then I think about all the times he’s lied and convince myself he’s lying again and I start to obsess over it until I’m all the way down the rabbit hole. I want to know how you guys were able to move on from past mistakes and start to build trust again. I still love him and want to make things work, I just need advice on how to get on the right path. Thanks in advance!!
