Husband lied

So my husband went to a bar Saturday night and didnt tell me. While at said bar he and a co worker(girl) from work were calling each other and then end up at the same bar when i asked about her all he could say was that he didnt cheat. And when he got home from the bar at 4 in the morning he called her to see if she got home ok. But yet never once checked in with me. How would yall react? And what are you thinking? Am i over reacting for being done with him because of him lieing and not knowing what to believe
