I was born in the year 1965 (Snake), my partner for 17 years (Ox) left me. Are we still meant to be?

We've been together for 17 years. Never married, just live-in. We've had our ups and downs. A lot of trials, moments when we split up, but keep finding ourselves back into each other's lives again. Earlier this year, he left me for another woman (I don't know her animal sign) Is this another trial for us? Should I give him up? Are we still meant for each other? To fight for him, us. Or give up? We were supposed to get married this year. At the start of this year, on top of my problems with my partner, The trials come one after the other and pile up. From my health (HBP, dental, etc,.), my finacial, family and even with co-workers from time to time. What should I expect for the coming days, weeks, months? I've been so down and been having bad thoughs. Please answer. Thank you.
