Of course your comments come accross as guilt-tripping.
If you cannot see that your comments, however subjectivly meant, and whether well-meaning, contain aspects of what comes accross as guilt-tripping, then a little reflection may assist.
When someone has already shared about a history that amounts to manipulation, and could even amount to emotional abuse, what do you expect your comment, repeated below, would elicit?
Also, what are you teaching your children? That it is OK to be unkind and not consider older people’s feelings?'
"Be kind" is not a magic phrase to prevent strong expression of opinions against perceived problematic thinking. I don't try to come off as charming when calling out something that could impact negatively on someone who seems to already be suffering & trying their best to get through something that could potentially amount to abuse.
But my main concern is for OP @merrychristonabike. This last bit is not a response to FillyFillyMe.
@merrychristonabike I want you to feel supported and validated. You may come accross many people who do not understand what it feels like to have parents who dismiss your needs, minimise the impact of negative behaviour against you, and make you feel selfish for expressing your needs, but that doesn't mean your experiences are not real. And there are some who do, and will understand.
May you feel heard, seen, supported and even loved by the healthy people and in the healthy relationships you encounter. There will be people who understand what subtle control looks like. You may second guess yourself sometimes, but the fact you make concessions such as making yourself available before and after the time you want to set aside for your family (protected time), shows you are trying to make room for your parents even though they cause you problems.
But it is important to feel OK about having boundaries. By choosing behaviour that forces you to entrench boundaries, your parents choose the consequences of that behaviour and that includes you setting boundaries. Don't feel guilty because by choosing to disregard your needs and boundaries, the consequences of that are on them and they are choosing to force you to have boundaries.
Don't ever be made to feel (I say this because sometimes this happens, sometimes from well meaning people) that any bad thing that may happen in the future is because you set boundaries. Or that you'll regret setting boundaries because of bad things that happen. No one is powerful enough to impact the future to that extent, and no two situations are exactly the same. Please let go of the burden of feeling you must balance everyone else's needs but your own. Please stop feeling like you are responsible for managing your parent's feelings or reactions. Also, remember, the Internet is full of people who many not have had your experiences. Sometimes people mean well, but what they say may be damaging. So take everything with a grain of salt and continue to get the healing you need. If therapy could help, maybe something to consider. Good luck with everything. I hope your future Christmases are full of joy, and the magic of Christmas.
