Hello & Welcome to Just Answers.
Yes, I think you should get over it and trust him, and then look to find out why you're so obsessive. That level of obsessiveness isn't really about trust, it's about emotional neediness on your part, and no one person will be able to make you feel secure enough inside yourself if you don't already have that in you. The fear just hops from one spot to another like a person who changes their clothes. It's exhausting for everyone involved and drives the patient batty over time.
I wonder if you're suffering from anxiety
or OCD in other areas as well. If so, this is something to speak with your doctor about so that it can be treated at the source: your brain chemistry, and how you organize your thoughts. You can also work on controlling your thought/feeling/behavior cycles with CBT techniques. If you go to this site
you can start to learn ways to get relief from fears that are troubling you.
Once you've got yourself and your emotions settled out, then it's time to look fairly at his behavior and decide if he's trustworthy or not. When your head is clear, you can hear your inner voice better and you'll know what to do. This will give you much better success than trying to nail down facts like a detective and weigh them out, which is nerve wracking and painful.
My best to you.
