100% Gemma isn’t her best self when she’s with Luca. I think it’s moved far too quickly and she now feels like she’s married to the guy. That’s suffocating her and the reason why she seems so miserable is that I think she’d like to have fun and explore her options rather than be wifed off from the jump.
Although she comes across as quite dominant and she can definitely hold her own, I think she’s scared of conflict. I feel like she feels she let it get out of hand and it’s gone too far to turn back now. Because imagine the scenes if she told Luca she wasn’t feeling it.
