Oh, I so understand how you feel. I was fortunate enough to be feeding my DD for 19 months (never planned on being one of those "Hippie-freaks" who feed beyond 12 months - well, that's what I thought before I had DD). At about from about 12 months she only had 4 feeds a day (first thing in the morning, before her day nap, before bed time and 1-2 overnight feeds. She also had some cow's milk. By 18 months she had replaced all but one overnight feed with milk (she asked for milk, was not interested in the bottle. I then started to think about how to stop the overnight feed (felt like I was left with the least desirable feed, in the middle of the night). But when she started asking for water instead when waking at night, I was sad. I started to actively offer the breast (something I hadn't done in months), but she just wasn't interested. I was about 3 or 4 months pregnant, so my milk had probably dried up.
Although I was glad that she had stopped BFing on her terms, I was so sad not to have this lovely tender bonding time with her anymore.
But you know what, you will both adjust and find different ways to bond.

Lots of hugs!
