What does it mean when your husband keeps talking to the same woman?

Caught it my husband talking to a woman multiple times (3 times) & when I confronted him he lied and said it was different women every time. I then found a number in his photos and he said it was another girl and not the same girl. I looked the number up and it’s indeed the same girl. Does he have feelings for this girl? He keeps lying about messaging her saying it’s other women?!
