Love wants the loved to be happy. Thus, love respects the will of the loved. If you love her, you will respect her choice. At the same time, she should respect yours. Each of you should be free to pursue the spiritual path you choose. That is what love does: it gives, it does not restrict, demand, or limit.
And if that is not possible, then practice secretly, silently, in the very act, without disturbing the peace of mind of your spouse.
“Nothing is easier than self-deceit. For what each man wishes, that he also believes.” —Demosthenes
"Do not worry; cultivate the habit of being happy." —Samael Aun Weor
