Is he cheating on me ?

I dont think he's cheating at all. I understand how you feel cuz I struggle with jealousy too. Ive found it best to keep any and all jealousy feelings away from my spouse. I vent them to friends, journal about them but I do my best to not share them with him because it is a relationship killer. I dont think he's cheating at all. do all you can to combat those jealousy feelings. Read about how to get rid of them on the internet etc. Good luck! :)
