Re: why men never say those 3 words
some men do, but i'd say they're in the minority.
i agree basically w/ blanca in her post.
theres a simple answer to yer Q, and a more complicated one (u can make both plural too if u like).
simple: i think as time goes on most men realize (some women too) that its just words and actions speak louder.
Also men can get comfy/lazy faster than women (but women retaliate w/ less sex...or actually preceed mens "lack" by doing thus pre-emptively) and fall off the wagon so to speak.
Also, over time resentments start to build to the pt of blocking loving words/actions on both parties accounts.
complicated: there are some couples out there for whatever reason, upbringing, experiences, etc, don't hold to hearing "i love you" at all. again, its about couples meeting each others needs.
Also, some lucky couples speak a silent language as it were and can say the words by a look, a gesture, or just going about their marital business as per man and woman duties/chores for example. i.e., they don't need much reinforcement/reassurances from ea other. (yet this too is rare)
Also, there are many males out there/here, and "i love you" is one phrase thats hard to lie about (for long) as it carries alot of wgt and responsibility w/ it. Men feel they carry enough responsibility as it is.
As for my W & I, we def could say it more but i am action-guy
1st, and put my emphasis there. If my W was more action oriented, she'd have little trouble w/ me on many issues in our marriage but like most women i've known, its alot of head games i have to deal with as words can be false misleading etc, as time proves over n over.
