I think a lot of pet owners here are giving you a very hard time.
You aren’t trying to abandon your pets/the responsibility.
This man is going to be your husband soon. So all these bees that wouldn’t put their mothers, fathers,siblings in front of their husbands think it’s okay to put pets in front of him because “they’re family”?
Yes I agree pets are a responsibility and do become family, but this was an unforseeable side effect of owning birds. both OP and her boyfriend love the birds and care from them, as you would know if you actually read all of OP’s posts before getting your animal loving panties in a twist.
Parikeets squaking can be very difficult to listen to for literally MONTHS. How are none of you udnerstanding that? OP only has to deal on the weekends but he has to deal with it all day every day, how can you not understand that is an issue? For anyone, let alone someone with existing issues.
If you honestly want to marry this guy, the parikeets will need to be rehomed since you’ve done everything else possible to try stop them being an issue.
The only other option would be your SO moving out, but how will that work once your married? you and your hisband live in seperate homes because of your birds?
I would do what you saw best. Yes it will hurt, and you love them, but especially if you can still visit them you may feel a lot better about letting them go, at least for the first couple of months or something.
I am sure you can both get another pet down the road that would suit you both as a couple, that you would never have to rehome.
I know rehoming is hard, I had to do it with my rabbits, and it really did break my heart, but I didn’t have another choice, I had to move and was not allowed to bring them with me to the new home due to the landowner.
It isn’t something that will amke you a bad owner or pet carer, it’s just something you may have to do for the sake of your relationship.
