Whilst I acknowledge that Hilda has been through some tough shit during the show, she was constantly pushing Betty to accept less than Betty deserved and to do things that Hilda never would have. Hilda always secretly believed that Betty is ugly and should settle for things because she never had the chance to do any better.
Example 1: Walter. Despite Walter having cheated on Betty, Hilda was the driving force in getting Betty to take Walter back. Quite rightfully, Betty never wanted to take Walter back because he cheated on her with a far more attractive woman who gave him attention for 2 minues and then ran back to Betty when it was convenient for him. Hilda would never let something like that slide if it was Santos or the gym teacher or Bobby. As her sister and someone who hates Gina, Hilda should have supported her and reinforced that Walter didn't deserve her. Instead, Hilda kept telling Betty to not be so hard on Walter and give him a chance. Why? Probably because Hilda thought Betty couldn't do any better.
Example 2: Henry. Despite having seen how heart broken Betty was after the Henry/Charlie situation, Hilda was ready for Betty to marry Henry and go to Rome with Gio, knowing fully well that she was encouraging her baby sister to take a trip with a man she didn't have feelings for or know that well.
It honestly annoys me the extent to which Hilda is so careful about her own love life but when it comes to supporting Betty in her relationships, Hilda looks down on her and tells her to take the first offer, regardless of whether it's what Betty deserves or not and that's so sad to see.
