Does he still love her?

[The Boss]

part 1 should he have them
No and yes. He could have them because his daughter likes those picture and she's over she could get home sick and the picture could comfort her. the no is because like you said your married and have two kids he should respect you have tons of pictures of you not of that women

part 2 what i think
I don't think he still loves her,but what I think is that he might have some pictures of her because his daughter could told him to see them.

part 3 should you let it go
No but you should hold it over him when the time is right. it should be your trump card when you two are fighting.

PS you should get his phone and check if he text her or calls her at anytime
