Questions: Relationships

Long story short, I'm concerned that I may come off as being overly rude and hypocritical if I tell my girlfriend that she's getting pretty chubby while I've always been plus size.
For context ever since we known each other I've been plus size while she was quite fit. Last year she started packing on some extra weight and she's getting concerningly chubby.
Would it be an asshole move to ask her to try to get back into shape / offer to cook healthier meals for her?

We started dating at the beginning of this year, so it has already been about 4 months. We have exchanged photos and have been calling almost every day, we practically sleep on phone calls. We are going to start video calling by beginning of June and see what happens.

I have my university studies left to do for the remainder of this year, so my timing is not great at all. I have certain time gaps which I can see him:

End of June, End of October, November or beginning of December. I was going to discuss these options with him as he is also saving me money. I was going to visit him for 2 weeks and if things work out, I will visit him again in February next year for a month before I start university again.

I am only concerned about things becoming boring or stale, and usually the "honeymoon" phase ends at 6 months. So, I thought about June seeing him then, but I thought it would make a good test on our relationship too. I've known this guy online for 3 years now and we decided to take things to the next level. We watch movies, play games together, take photos and share them, we do a lot together. It is comforting.

I would prefer seeing him because of his own circumstances. What timeline would be best to see him? I can discuss with him later.

Did you guys eventually ended up getting married or was it BS in the end?

I’m in a relationship and we been together for 5 months. Like at the beginning of our relationship I couldn’t stop thinking about him. But I can’t tell if this is love I’m feeling or I’m just don’t want to lose him. Because I don’t want to lose him. I would miss him so much but is it because I love him? Like I don’t get a butterflies but I do excited when I see his text or call. Like I use to get butterflies when he runs his fingers on my back. I also do think about a guy but I never really like him but I do think about him. But I can’t imagine kissing him it makes me sick to my stomach. I can’t really imagine kissing anyone else besides my boyfriend. I do miss him when I’m not around him but it’s not the end of the world or a big impact on me.
Is this love or am I’m just comfortable?
