I find it difficult to form a close bond with someone who has underdeveloped communication skills and is unwilling to work on them, or lashes out instead of wanting to participate in healthier patterns of dialogue. that’s a pretty firm dealbreaker for me.
If someone doesn’t respect your boundary: the answer isn’t to try to convince them they should. Or to tell them how they’ve violated it even if they don’t agree. The answer is to hold your boundary and resist the need to explain.
Boundaries are for YOU.
