I'm not going to wear my engagement ring
Why don't you want to wear the ring?
I feel like my boyfriend doesn't treat me the way I deserve even with an engagement ring.
Wearing an engagement ring is a symbol of your love and devotion to one another and you shouldn't break that bond. Talk to your boyfriend and make sure you let him know how you feel before you dive into marriage.
What does talking about my feelings have to do with wearing an engagement ring?
I'm just saying that he might be upset if he sees you aren't wearing it. You two are clearly having issues, and I think you should talk to him about those issues.
