One of the toughest hands I've played - 200NL

[Trikkur]

Villain is solid probably a 2+2er, I feel like I can fold the flop to make my life easier, but I felt like calling was correct. The ace is a good and bad card. It hits my likely range of 2 pair, but I feel like if I bet he's still calling with 100% of his range that he raised the flop with and I'm going to be lost on the river. Should I of folded flop? If I don't want to fold to the raise give me a generic line for the rest of the hand and also the specific line for the A that turned. Thanks
