Dear Thalia:

A heterosexual man who chooses  one woman for a monogamous relationship has to give up all potential relationships with other women, no matter how attractive they may be, not different  from a  bisexual man having to give up all potential relationship with attractive men and women once  committing to one  individual. In other words, being bisexual does not exclude a committed, monogamous relationship, I figure.

But he wants to experiment with a relationship with a man, so obviously he  is not available for a committed, monogamous relationship with you, and you stated that both of you are monogamous.

I was impressed reading from you, how  mature and rational you are, particularly for a woman in her early twenties (you started dating in high school and have  been in a relationship for 2.5 years).

I think it will be best if the  two of you live like friends and roommates only at this point for the rest of the duration of the lease and then live separately. Better you sleep in separate rooms, or if there is only one room (a studio apartment, let’s say), then sleep in two separate beds or mattresses a good distance  away from each other. A divider to separate the sleeping arrangement may  be a good idea. No cuddling or such, no physical contact, I think is better. Place  the physically intimate part of the relationship in the past where  it now belongs.
