When I was growing up, I used to be quite close to my DM. I moved out of the family home some twenty years ago and since then, my DM has become less and less interested in me.
I'm married with two DC. I think most grandparents are quite interested in their grandchildren. If I send my DM photos of them or message her something about their achievements at school, she doesn't even bother to respond. If she visits, she doesn't really engage with them at all or I much. She doesn't really make conversation and so it's always me who initiates it. My DM doesn't phone me or invite me over to see her and I don't think she's ever asked me how I am. If i see her, it's because I invite her over to my house.
Recently, I've stopped making the effort to keep in touch for a few reasons. It would always be me who made the effort to keep in touch and since I stopped making the effort, she hasn't bothered to make contact with me at all. In the past, even though I didn't like always being the one who made the effort, I did it anyway. However, I've recently found out that my DM told my biological father (my parents divorced when I was a baby/toddler) that he wasn't my father when I was a baby/toddler and told another man that I was his daughter.
When I was a teenager, both my grandmothers told my sister that this other man was my father. At that time, my DM told my sister and I that that wasn't true. Now that I know what I know, I don't think she truly knew who my father was. Recently, I tracked down the man who was told that I was his daughter. He hadn't seen me in about thirty years and told me that he truly thought I was his daughter. A DNA test proved we were not related. So, I did a DNA test with my sister, which proved that we shared the same parents.
I haven't told my DM about what I know, as I know she will just say something like "well, I always said your biological father was your father." I am upset by the fact that she'd told my biological father that I wasn't his daughter, which of course led him to treat me completely differently to my sister.
So, now that I know what I know, I feel really reluctant to make the effort to keep in touch with my mum. She hasn't once asked me why I haven't been in contact. If I don't contact her, I wonder if she'll ever bother to contact me.
WWYD if you were me? Should I pretend I don't know about her telling my biological father that I wasn't his daughter? Should I make the effort to contact her when she doesn't seem to care about me?
Also, I told my sister about all of this. Instead of showing any sympathy whatsoever, she seems to have decided not to contact me either any more.
