Relationship issues

OK so me and my man have been together for almost 7yrs and about 3yrs ago when had a really rocky patch he cheated and ever since then I have been having some trust issue now yes I made the decision to take him back I understand that but I feel like I'm just at a point where I don't know if I really want to allow myself to trust him.. what do I do if I know the love is there but I'm scared to go 100 percent back into it with him? Don't be judgemental I just want honest feedback. How do I move past the past so I can have a healthy future?
