Agree.
Consider ways to strengthen the relationship after the argument you had with your fiance. If he’s STILL upset and distant with you…it seems unreasonable to think of receiving a gift from him/his mom.
Also, I went back and read your post and you mentioned that your sister tells you that her MIL will be sending her an Eid gift. Your MIL and fiance/husband…will be different from your sister’s MIL/in-laws. Your cousins’ in-laws…your friends’ in-laws…your neighbors’ in-laws will be different from yours. If you continuously compare your situation with others…it can result in feelings of jealousy/resentment…which are not a healthy state of mind AND which can potentially destroy your relationships.
