Everyone should be, as you put it, "in Catholicism". There is only one true religion, and Catholicism is it.
Though I take no pride in it whatsoever, I am divorced. It's a horrible thing and there's nothing "good" about it. I am not free to "remarry", and I live celibately, while my wife is taken up with another man whom she "married" illicitly and, of course, invalidly. (To be fair, so far as I am aware, there was no involvement between my wife and her consort before our separation, seemingly she met him later.) I am still bound by this union, and matters will probably remain as they are for the rest of my life. Bachelor life does have its points, and thank God, my son is with me full-time, I homeschool him (I am retired), and he hasn't seen his mother in years. My own mother, who lives with us since my father died, is basically his "mother figure", and a good one she is. She has been gravely ill, and received Extreme Unction a few days ago, thankfully, she survived her health emergency, and has adopted a new life of prayer from her sick bed.
I do condemn divorce in no uncertain terms, even though I myself am in that situation, and no divorce is ever 100% one spouse's fault or the other. I am a practicing traditional Catholic and I attend the TLM, everyone knows I live celibately, and no one's ever given me any grief over my life circuмstances --- if they have an issue with me, I'd much prefer that they say it to my face, than talk about me behind my back. So far as I am aware, no one does that.
I hope this helps. Pax te.
