Help, im in love with a biual that pretends to be straight. He has alot of old habits. Do i need to worry?

ok so i love my man we do everything together everything id say is 90 % good the other 10 is becuz of lack of communication and trust. we all know its hard to trust sum1 if they lie to you. I recently moved with him and i now see that he cont. looking at wit men and even has a dating profile where he put new pics up...looking at most of the pages i can see that alot of them r very into placing nude pics out there...this drove me nuts becuz thats how i found out bout it and he cont. to keep a profile and log in at times. For sum reason imnot suppose to be worried bout this other side of him becuz he says he doesnt adventure into it...but can i believe that when he is bi and has me but i cant give him that and he looks at it so i feel like he wants it but behind my back...or it could be just how he is and wanna keep it to himself. like i do live with him so i can see his patterns. he says when does he have time...but gays/bi..are so secretretive how will i ever know for sure. i just dont wanna be lend into a lie. like i feel ive given him all i can give and if i cant satisfy him in that way how can he ever stop wanting that thrill...im so scare to be cheated on with a man becuz i cant help that...i need advice on how i should go on bout this im not gonna leave him over it i just dont know how to get him to open up becuz i can figure this out to have a peaceof mind that its not being done behind my back....likei bought a and he has already used it...of course he aint gonna tell me that but momma didnt raise a fool...but i know its a hard thing to tell me like is this just something sum1 like him has to have to himself like a private thing that no one needs to know he likes and i should just not mention it what...i know this is alot so just answer what u can...dont get me wrong this doesnt happen all the time but when i see it it just drives me nuts
