Remember before deciding that only those that Dom says make sense will get a romance ending.
Amy has made it perfectly clear she will never leave her husband, her family comes first even above the MC. She will have extra marital affairs but nothing more. She won't subject her kids to it. Not sure if Dom will change that but as it stands I took that to mean sex is okay but don't expect anything serious.
Same with Maria. She's only looking for a bit of fun with a young guy, she already has a family and isn't looking to settle down with someone else.
Daisy and Alex are college kids just looking for a bit of fun.
Mayan I thought would be a full romance ending option but after that conversation in the coffee shop i'm not 100% sure anymore.
The only ones that stuck out for me as potential full on relationships were Jenna, Sophie, Hikari and maybe Dani.
