Does yuki still love tohru when he gets toghter with matchi?

Yes, but he admits to Kakeru (Machi's stepbrother) that he loves Tohru as (this sounds weird) a mother. Because he had such an unloved childhood, and was repeatedly rejected by his mum, he always felt that he lacked a 'motherly' figure in his life. when he met tohru, he realised that she filled this empty place.

haha. so corny...

but at least there isn't a love triangle and poor kyo gets to love tohru without any competition. though momiji does mention something near the end of the series... well anyway, that's a different topic.
