What does the communication style reveal? A parent is not a therapist, it sounds like OP has always been there for her dd. It's possible she cannot relate to her daughter's depth of feeling, I know my mother never could. That would be disappointing for OP's dd and it's easy to feel misunderstood and 'too much' if parents aren't able to support our emotional needs.
But what is this expectation of symbiotic perfect harmony and understanding?
The question is did OP as a mum regularly put her daughter down and criticise her character, appearance, life? If yes, that's abusive, no doubt.
Did op hit, routinely yell and swear at her dd? If she did she is an abusive parent.
Did she always sigh and act in a passive aggressive way with her dd? If eyes, that's also a sort of abuse, very unpleasant.
Did Op have controlling behaviour towards her dd, did she not allow her basic things, snoop her diaries, eavesdrop her conversations with her friends, put down or overtly praise OP's friends? if yes, that's emotional abuse.
Did OP always compare her children in a biased way? Always take sides when the dc argued? Did she disregard basic boundaries mollycoddling her dd? Well I hope not.
Feeling exhausted by your child's issues and troubles is perfectly normal, it's because we care. Some parents aren't amazing as regulating their feelings and that's horrible for their dc but unfortunately that's due to bad mental health.
I'd like to know what OP's dd has done for her parents? Does her dd listen to her mum when she has a worry or shares her experiences? Does she help her with practical things? Does mum? Without negatively commenting?
@KJCP I will say that texting your dd's husband when she told you she needed space was very ill advised, as you immediately tore down the boundary she bravely put up. And going on honeymoon with parents is extremely weird, did she feel she had to ask you to come? Does she suffer from anxiety and wanted you as a security blanket? As a mum would have declined that offer, it's most unusual.
I hope you can work it out. I don't believe you need therapy for that though. Just honesty, a willingness to listen and not be immediately dismissive and defensive. But it's possible that your dd is quite hard work and that she needs to get over that with some help. Having her own dc will help with that.
Abusive, vindictive mothers sadly do exist I am not sure the OP is one, only she will know if she searches deep within.
