Imo love is a fantasy as well and a psychological/emotional need for some people, more women than men. With sw/swingers relationships if a man is having his needs met (psyically) so does a woman (needed to be loved). They make a good team imo if decide beforehand what they want out of their rekationship and their long term goal.
About being truely loved, bitterness, revenge and resentment can be resulted from many other things not just sw. Marriages and ltr end for both sw and civvy people.
To OP, do what makes you happy and at peace and take your time with this man and disclose about sw when you think he is worth it. And be extra careful if your family/friends dont know because you are trusting this person with information that can potentially ruin your other relationships and reputation and in the end he might be as interested as you think he was.
Personally i love sw and do not intend to leave it to be loved by another person and i think genuine relationships/marriages can happen with you doing sw, its between you and your partner and your dreams and goals. Some people want true love, some settle for happiness and honesty and so and so.
Again imo, studies are based on human behaviors not the other way round.
Its not fair to call others delusionsal because they believe in different things. I think women on here are nice, smart and wise and if they choose to be married/partnered with i am sure it works for them and makes them happy. You are better at work and generally in life when your happy. If not nice to say that it will be short-term because no one knows. May be there is more study needed because it surely doesnot cover these women.
