I quit traditional dating years ago, I am not attracted to women my age so there is no
point in trying. Thirty years of dating has taken a toll. Res Ipsa loquitor.  
Good luck

There are many reasons we are here, your ability to leave will depend on why you hobby, you're ability to make a commitment to the relationship, and many other factors some you control and some you don't.  

Good luck

the answer to that question is a function of the individuals involved.  (Thank you captain obvious).

How important is the physical aspect of the relationship to you?  How important is it to your proposed significant other?  If there are physical things you enjoy doing that your SO finds disgusting, my guess is you'll continue in the hobby in some fashion.

Interpersonal compatibility is more important to me than than the physical.  I see the providers I see because I get along well with them.  We invariably spend more time chatting than fucking

If I find someone to love, I'll stop the hobby and be faithful to that someone.

I have certainly been able to revert to something monogamous, twice.

The second time was probably the more compelling example.  Fell in love, was sexually enthralled and very satisfied so that I was able to focus all my desires into this good, giving, game relationship.  

It failed because I didn't know which personality I was coming home to.  Volatility kills relationships, especially, I think, as we get older.  Ultimately I need passion, and consistency.

Good luck!

My take on the subject, depends upon the individual.
In my case, yes I was able to walk away from the hobby, and not for the reason of a relationship.
I walked, due to all the instability of the hobby. I know, no strings attached, however, when dealing
with providers, and wondering which mood is going to show up for a date, well in my case,
the guess work and risks took a toll on my ability to enjoy and justify the hobby experience.

I am very picky, about whom I spend time with, and whom I compensate with my hard earned dollars, and the pool is very slim when my preferences are applied.
So rather than bitch and complain, I left.

I have a good relationship with myself, as well as an ability to control my urges to fuck, and while
I do get horny, and am always on the lookout for that female diamond in the rough, I usually
am Just in cruise control, and only actually hobby a couple times a year.

Whatever you do decide, best Wishes in your pursuit of happiness!

It depends on what your normal is, if cynicism and emotional disengagement is yours and thinking of men who have these forms of emotional views as whiteknights and manginas, you might have a hard time returning to civilian life.  

If you can respect a woman as a full person, maybe.

Best of luck.
I will light a candle for you and her.

... you don't need us to answer it for you.  And I think you've already answered it.

You don't know if you love the woman; instead you look at the proposed relationship "like a business arrangement with benefits."  Business arrangements are almost never exclusive.  However, business arrangements are governed by contracts.  Marriage is a contract, a mutual give-to-get.  But contracts can be constructed in different ways.  There are marriage contracts that do not include monogamy as a condition.  It appears, however, that in this case your intended spouse will require that condition.  Can you uphold your end of the contract?

You say that the proposed relationship could be very beneficial to you.  But how will it benefit the woman?  You've admitted that if you could have a lady fuck you up one side and down the other, you still feel you're going to be wanting/seeking something new and different--considering how easy and available it is.  What will you do if you someday see a provider whom you think could be beneficial to you?  

I was monogamous for nearly my entire life.  The main reason I was monogamous is that I loved my SO or wife and because of that would never do anything to hurt her.  I entered the hobby only because I was sure my wife no longer loved me.  IMO love is an essential component of a monogamous relationship.  When all else fails, when sex isn't as hot as it used to be, when wrinkles and love handles start appearing... love is still there.

You know yourself better than anyone else knows you.  If you question whether you can remain monogamous in this proposed relationship, it's for good reason.  If you respect this woman and have any love for her at all, don't enter a relationship with her until you're certain you can respect her wishes.

Here's one way to ascertain whether you can be monogamous:  exit the hobby.  Today.  Stop seeking "bucket list" candidates... today.  Begin your monogamous relationship with this woman TODAY--even if she is not yet ready to exit the hobby.  Try monogamy for a few weeks, a few months.  See how you feel about monogamy after that.
