I think he's cheating

So we've been together 2 years he was a picture perfect guy but of course we both had our faults and our relationship got a little un healthy as we worked on it and things got better my bf proposed and we both wore rings... so months go by and no planning of wedding and as we're planning to have a baby yet never having sex especially around my fertile week ... so he's a server a picture from his job goes up online rewarding server of the month in the picture I can clearly see he dosent have his ring on so I bring it up to him and he claimed it was an old pic and blah blah blah but yet there was a new employee who just started working there in the picture..m either way we talked and I decided to let it go ... a few friends said to pop up on him at work but I just didn't want him to think I was crazy even though he calls me that evry day ... so a few months again go by and he forgot his work shirt and asked me to bring it .. so I drive an hour to bring his shirt and this guy walks out with out his ring on ... so when he realized he didn't have it on he stuck his hand in. His pocket ... where he was keeping the ring and started to shove it back on when I asked him to show me his hand he refused so grabbed it and when I took his hand out his ring was barely on and he claimed that it came off because of how I took his hand out... so than I took off jo shirt for him ... an hour later I pop up now and he once again didn't have it on this time I grabbed his hand since he didn't see me approach and he said well after what you just did I took it off. All day he ignored me off and on one sec he was sorey the next I'm crazy finally at 10 pm he admit he took it off to clean but then says 10 min later that he's just saying that to shut me up than another 10 min later is saying he really did take it off to clean and I'm just crazy and that's why he can't be honest
