in truth, the love addiction is almost always intertwined with a sexual fantasy if not consciously,then subconsciously.
but what pure yid says here is a real truth as well.there is an inherent addiction to specific persona usually the opposite gender that is not nessicarily connected directly to lust.
Emunah helps with this very much.the idea that no matter how strong your emotional feelings are towards a person,when one realizes that there is One Creator and intrinsically that idealized person is a mere mortal, and is born, and dies, that sweats like me and you,and stinks up a bathroom like me and you when they have to do thier business,and that thier barf smells just as bad as yours,and that even that perfect person has serious flaws and issues whther you see it or not,that it's God you put on a pedestal and no one else,this awareness and contemplation goes a far way into helping break the unhealthy attached feelings one may have to another human being.
Rav Pam experiences this with some of his students who were dumped after several dates,and in thier minds THIS WAS IT!!! and they fell into very severe depression thinking they somehow blew it,this was MY zivvug,and somehow it got messed up,this person was PERFECT for me and there is no one else like her in the world etc.. etc... and it took a while but he pulled bochurim out of this twisted thinking and they even thanked him years later when they were already married (to someone else) and realizing now that they weren't thinking (or feeling) clearly then
and He warned bochurim of not falling into that trap.
and so,a love addiction is real,its painful,its a drug of putting hopes and aspiration to a god to escape the pain of reality,but when facing reality,even if painful and dull at first,there is great and abundant blessing buried within.Appreciating what God allots to you,and that idealized god or a woman wont do anything for you.
