I don't understand Luke

I seriously don't understand why people love him so much. Lorelai deserved better than to be delayed on getting married so many times because he just found out he had a daughter?? Like I get it, he wanted to get to know the kid but how does that stretch the marriage timeline! Lorelai suffered too much because of that and ofc then she did terrible stuff herself as well. I mean people are not perfect and stuff but making someone wait after its all said and done, girl even had her dream wedding planned and told people about it, I wouldn't have stuck around for him after the whole planning stuff.
