(FWIW, I didn't fall in love with my husband, nor my son. I have great and loving relationships with both. Falling in love, IMO, is an optional extra and not the be all and end all. That's just my opinion though, and you're welcome to disregard it.)
ITA with Lady Zaidie - I think being 'in love' is really over-rated and doesn't have much to do with long term lasting love.
Is he saying that he doesn't love you anymore? Or that he isn't in love with you...they are two different things to some people and I'm not sure what he said or meant.

And I second the counselling suggestions, if you can. But you have to have two parties willing to go to counselling or to work it out.
Not saying he's not, but what worked for me was- I got on with what I had to do. I acted as though that was it, all over, sayonara - that was my way of coping so that if he didn't want to work it out I didn't have that crushing blow again ITMS.
