Trust gets broken all the time in relationships, it is a very common experience in relationships. I see this as the number one reason that people seek out couples therapy in the first place.
Navigating the complex emotions that come from this can be overwhelming and you do not have to do this on your own. I know how much it hurts. My partner has broken my trust and so have I, and I can say we are stronger than ever in the 10 years we have been together.
It is something that people are often embarrassed about and feel deep shame about. Having a relationship injury does not mean that your relationship is over, you can work through it.
And it is important to know that couples therapy can help you because it is hard to do this on your own without support. Support can be lots of things, connecting with your spiritual community, reading a couple's book together I can give you recommendations! Support is not just going to couples therapy, but please know that there is help for when you are hurting the most.
There are three basic steps to repair relationships after trust has been broken due to various things like betrayal, gambling, or lying. Empathize: listen to your partner's perspective and accept their feelings.
