Ok- no marriage advice here. But girl- you are pregnant and entitled to all the feelings. (entitled to them regardless but helloooooo preg hormones).
eh- can you talk to hubby in a “my emotional state just.cant.handle you riding my horse right now”? Phrased in a different way of - it is not you, it is me may help?
In any case, you are not giving up the dream, you are postponing it or let the dream change. My dream has always been floating around on a ground skimming, beautiful, picture perfect hunter back at the 3’6. I ended up with a jumper who I event and trust me- he is no beauty and the only floating is my butt a foot out of the saddle when he launches over the jumps.
Also- I keep mine at home and good lord… some days I just can’t get out right after work. So agree with the above poster- stop pushing yourself. Get home, put those swollen sausage feet up and chill. Waddle out to the barn when you feel like it. If it is safe for you to ride, do it. If not- do ground work and get the horse working with you to keep that connection. Thursday I just wasn’t feeling it. Got on bareback (do not recomend bc you are preg, just to be clear) and walked around. My friends were out having lessons and “working”. Eh. My dream is to have fun on my horse…
It is OK for dreams to change or push them back. Good luck.
