I think Patrick is an ASS for questioning Alla, but I get why he is so invested. He has seen his best friend go through three divorces, and has presumably had to be his rock during those times. I would be questioning and side eyeing my best friend in the same situation, and they would do the same for me. Like it or not, but Matt clearly wants love. I doubt someone would get married three times and engaged a fourth without being a romantic. He strikes me as a love addict. Issues of worries for Alla and her son aside, this will not end well most likely, beause of Matt, not Alla, and I can't blame a best friend for being upset. He is going about it the wrong way but I get his frustration.
