Is this suspicious behavior ?

He’s emotionally cheated in the past. There could be more physically but I have no clue/proof.

My husband was at someone else’s house after work. For over an hour. Never been there before… and didn't tell me who's house it was. He ignored my calls the entire time he was there. Then drove around and then finally came home and sat out in his truck for over 20 min. he finally told me it was his friend Oscar’s house that he was at, that he saw him driving and just followed him to his house to say hey.. but I asked him later where he went and he told me his friend Oscar called him and told him to come over… who knows what’s true on that and he hasn’t been over there since.

I’ve yet to meet Oscar and he’s still not been there since. Or talked to him since then. He only left said house after I started driving that way to see whose house he was at. (We share locations and you’d think he’d realize I do check everyone once in a while since we have a now 2 yr old). He drove around acting like he was headed to a friend house that we’ve been there before and then came home. It just feels weird and his multiple stories of it don’t add up.
