im overthinking this?

my husband took home a key flashlight from an academy thats near his workplace. i just have a bad gut feeling about it. that academy is full of young women working there. since he always go places while working, what if he went to that academy to fool around w the women? hed go out of town during his break to eat. he tells me he spends more than an hr, just to go smoke. and never follows the break time limit, he goes over 30mins and over 10mins for his breaks. he basically just plays around, getting easy pay. he no longer calls/txts me too. just maybe, maybe this is a sign hes cheating on me. or im being ridiculous? overthinking this? he does have histories of cheating. he got cheated on, he cheated, shit, his whole fam are fking cheaters. i just knew all this after 2yrs of marriage. i just wonder why he even got that key flashlight. hes a machinist, his workplace wont have anything to do w that academy. the academy is k-8. and the flashlight key looks like its been used.
