Could you please fix my sentences?🍋🍋🍋
I really want to make them sound casual a natural!!
How would you say this??
Please please brutally correct me

1. Relationships are funny. They seem super firm and solid but they really are fragile, easily broken more than anything else.

2. I really didn’t want to get deeper with him because I don’t see future with him.

3. He is too weak. it seems like he can’t even protect himself.

4. I can’t make a promise with him that I know I can’t keep it.

5. English has been my number one priority but sometimes I can’t help but ask myself "is it worth it to put in this much effort?". Yes it is of course. And besides for English, what else should I do?
(I know "what else should I do?" sounds a bit weird, I want to say English is the only thing I need to do)
