Joe or Terry?

Ok, so Avonella is 32...cute...trendy, just got married to her partner of 4 yrs, Terry. They were friends for 6 yrs so they've known each other for 10 yrs. She never saw Terry as her lover nor patner. He was a confidante. She confided in him about things in her life and that was it, but one thing led to another and it got serious.

Terry has been Avonella's only partner since Joe. Joe is Avonella's college sweetheart. Joe, Terry and Avonella were all friends back in college and back then Avonella would often ask her now husband Terry, advice on Joe. Avonella and Joe never broke their relationship off. After college Avonella moved and they lost contact...which was her fault. For yrs Avonella was hopeful she'd find the love of her life Joe again and work things out, but she didn't have that luck.

Well, how about two weeks after Terry and Avo tied the knot she bumped in to Joe. Yep! The Joe she put off marrying Terry for. Not only did they find each other but she find's out that Joe's also been searching for her. They still want each other. Even though it's been so long, her feeling's for Joe are very strong and she's curious to know what could happen between them.

QUESTION: Should she forget about Joe and be faithful to Terry who's been there for her? Or, should she separate from Terry and see what may transpire with Joe? Doesn't she owe it to them all to find out?
