Male and female cancers what would you do?

You're in a relationship with someone right? And you know deep down inside that you have done some things that your mate is aware of that makes him or her start to feel insecure again and not able to trust anything it is you say or do. What do you do? What are the ways of reassuring a cancer? I am asking this question on behalf of my boyfriend who is a cancer and so am I. He has done some things in which he has owned up to that it now has me wondering and feeling insecure again, and feeling I cannot trust him. I must say it took me sometime to let my guards down with him, same with him except I let mine down a bit earlier than him. He knows what he does or has done is wrong but now he feels that no matter what he says I will not believe him, which is true only because he's caused me to feel this way and it's going to take me some time to be able to trust him again and gain my security back into this relationship.

In your opinion what can he do? I honestly love and care for him; I am willing to work pass all of the things that he has done, however I feel that he has to do something to gain my trust back and make me feel secure again where I can believe what he says with confidence. So what is that he can do? Help me out on this cancers.

PS: I love you Cancers, we are the best no matter what anyone says

Alotttaaa sex ,and stay distant although we love hugs. But just keep yourself busy and do send him a txt time to time as for him to make u feel secure? Nudge him and go a movie and just forget ,BUT us cancers don't forget shit. And it always ,always will be behind the back of our minds. That's why once i forget u it's for gooood reason. But feeling secure we just have to learn to let go and do things to better ourselves as well.

Forget the problem, i know you can if you really love him. Show him again your affection.
