I'll try to keep this short, any help would be really appreciated!
My parents separated when I was in my teens and my dad got a new partner. I always got on with her well. 5 years ago my dad passed away. Just before he died, him and his partner married. I use the term "stepmum" for ease of narrative.
Together they owned a holiday home and me and my family used to go there for a week once a year. This continued after my dad died. About 3 years ago she got a new partner. I never had a problem with this and he seemed fine.
I'm not very close to my stepmum but we'd message and phone every now and again but this has reduced over the last couple of years. Last year via text she told me we couldn't use the holiday home because they wanted to use it for the whole season. I replied saying that was disappointing and I felt we'd drifted apart since she started her new relationship.
She hasn't replied and refuses to speak to me. I sent her a Christmas present but heard nothing. I don't know how to approach this, I don't want to alienate her further but am perplexed as to what I've done wrong. I don't like conflict but need to sort this out. She has things of mine and things of my dad's I would like if this is to be the end of our relationship. We don't live close to each other.
Any idea how to approach this sensitively?
