We asked my stepmother and father to stop contacting us last year after a long history of trouble with them. We tried everything to find a way around this but things were getting worse and worse with every interaction, so after a lot of soul searching I asked them to leave us completely alone until they are ready to actually sort things out with us, rather than keep doing abusive and hurtful things and then gloss over them and pretend that nothing happened. Since doing that we also moved house.
My SM was determined that she was going to carry on sending cards and money even though we asked her not to. When she realised we moved she started to send things to my MIL's house. Not only do I find this incredibly disrespectful, but it puts MIL in a very awkward situation as she's seen how upset I get every time she passes these things on.
My SM has absolutely no qualms about using people or putting them in an awkward position so long as she gets to plough on and do what she wants. I've just received an anniversary card, again forwarded from MIL and I don't know what to do about it. I'm tempted to just give them our address so that it takes MIL out of the equation, but then it's like she's won with her high handed bullying tactics. Unless I return it to MIL and ask her to return it to them and ask them to stop doing this, but she won't; she lacks confidence at the best of times and has recently lost her husband so it's really not fair to put her in this position.
Any advice please?
