“Every weekend my partner stays with her ex husband because that is where her horses are and it is also nearer where she works on Fridays and Mondays. I have had nearly enough. She says she loves me but we never have weekends together. I think the universe is saying something loudly to me but whenever I try to talk about this I get tears and anger and ‘we will talk next week’ and ‘I love you but I am busy and I am tired and I am looking after the horses.’ I don’t know what to do anymore. Please help.” (Edited)

Go with her....
“Pushing the system” in such a manner will expose, not what the Universe is saying to you, but what kind of a relationship you have with your partner and what kind of relationship she has with her ex-husband.
