I dated a young lady for eight months and thought we were both in love. Last summer, she travelled in Europe and had a 3-week long affair (including sexual intercourse) with a man from Australia.
Two weeks before she left, I’d given her an expensive promise ring and helped her pack. Our relationship had no signs of trouble.
When she confessed (I’d known something was up) I broke up with her. She immediately displayed extreme remorse. She visited me (four hours away), removed the guy from her Facebook account and said she’d do anything I requested, even move to my hometown.
I knew that’d only provide temporary relief. She then proposed a threesome with any girl of my choosing; I rejected this offer, too. For months, she was extremely remorseful. I remained unconvinced.    
Yet, I constantly think about her and am starting to think that, maybe, her commitment to me is genuine. And I’m hoping she’ll never cross the infidelity line again.
Are these offers signs of a woman who’ll go to the ends of the earth to keep her relationship intact? Or is this a larger problem dealing with self-respect, self-confidence, trust and self-worth?
(She’d previously said that her father was “non-existent,” leading her to make poor decisions and choices regarding men and relationships. An ex-boyfriend also physically abused her).
Should I give her another shot and start fresh?
- Confused

Time has helped you re-evaluate who she is and how you feel about her. Yes, she was weak and gave into the not-uncommon urge to experience an affair while far away and feeling free.
The promise ring may even have sparked a fear of commitment too soon. Those aren’t excuses for cheating; BUT she has shown continued remorse and desire to be with you.
You want to believe in her ability to re-connect and be faithful. So, give the relationship another chance, but do so as a team, not as the “good guy” monitoring her every action.
To start dating again, insist that she get counselling for the inadequacies she felt from an absentee father. She needs to understand more about making better choices, e.g. her offer of a “threesome” wasn’t the re-assuring answer needed for renewing a bond of mutual fidelity.
If you plan a future together, it’d be wise to attend pre-marital sessions to secure a foundation of trust, especially for when life’s inevitable challenges arise.

My boyfriend and I began our two-year relationship sexually charged for one another. I moved in with him six months later and our sex life started to lag – infrequent and I was the only initiator. He’ll only say he'll figure out what's wrong with him on his own.  
I had a herpes outbreak two months ago which has since cleared up but he wants to wait longer to be sure I know he isn't cheating, but I don't understand why he has no desire left.
- Frustrated

Romantic passion, followed by a rush to practical living, sometimes has a see-saw effect on one partner’s libido - the everyday concerns of chores, finances and the other person’s expectations, can dampen desire.
Also, the herpes condition may have him worried. He needs clear information about it, including when sex is safe or not.
If the chill continues, he may be depressed and need to see his doctor, perhaps a therapist, too.

After Mom died three years ago, ill feelings and accusations occurred. I’ve apologized, but haven't seen my family on the holidays since.
I took care of Mom as she lived with me, but there’s been no acknowledgement. I don't let my sister stay at my home as she gives me unsolicited advice. She lives far from me so we talk occasionally on the phone. My brother doesn't say much to me either.
- Isolated

If you want family in your life, you need to make compromises. A sister who gives advice is showing she cares - listen, but you don’t have to follow. Go out together for enjoyment, during her visit – movie, shopping, a lunch.
Invite your brother and his family for a meal or to do something together; do NOT talk about the care you gave your mother, or who said what to whom.
When they see you want their company, not just approval, they’ll respond.
