Seeing a guy with trust issues [I Need Relationship Advice]

I've been seeing this guy for about two months. We catch up 1-3 times a week and it's basically as if we are in a relationship at this point, just without the label. He had an ex which gave him some major trust issues. When I say I'm going out with friends he always thinks it's a date or I'm sleeping with someone. I told him I value what we have so I wouldn't risk ruining it by seeing other people. He doesn't believe me, whenever I try and reason to him it just sounds like excuses. Aside from the major trust issues with me seeing other people, he's such a great and genuine person. What do I do?
