Not great

I feel very conflicted about my rating, but I just didn't really love it, I guess.

I rarely enjoy a love triangle. It wasn't done badly in this story, but I didn't love it.
I also don't like the miscommunication trope. First of all, why did Gabriel describe it like that if he didn't sleep with Louisa? Secondly, I get that he was angry, but he could've just told her what really happened. Btw, he should have understood how angry and hurt Beth was when she thought he had cheated on her. In my opinion, he didn't have a reason to act like that at all.
I don't get why Gabriel is supposed to be such a great person. I did not like him and I don't get why Beth would ever think to choose him over Frank (oh, sweet, wonderful, amazing Frank). I also didn't really like Leo. I just felt like he was there for the convenience of the plot. Beth likes him so much, but we didn't really get to see any reason as to why he's supposed to be such a great kid.
I didn't like some of the plot twists either. Leo killing Jimmy? Ugh. Bobby being Gabriel's kid? No, you did not just do that to Frank!
