Should I let go?

There is this person that is so important to me, but with the problems I am goign through it is much easier for me to let go. It should teach both of us to be stronger, I know it would be the right things to do but I also dont want him to feel that I gave up. I dont want to, but there is something wrong that's going on. I hope I am wrong. I hope that my judgement is a little cloudy.
