Relax.
Nothing turns a guy off more than the smell of desperation.
Stop trying.
I met my husband the second I completely gave up.
I started thinking along the lines of how wonderful and capable I am alone.
Single is good. All is well.
That is not to say that you should become a recluse: just the opposite.
Start volunteering outside the Church.
My husband was a former Atheist (he had decided God existed before we met - but was un-churched). After joining the church choir with me, he quickly became Catholic w/o ANY request or expectations on my part.
The key is to stop trying to control; not have capital “E” Expectations; think outside the box; love yourself (in the way that God loves you); and most of all - chill.
Be “okay” with things if nothing clicks.
Frankly, I’m kind of surprised you’re having trouble in Portland. There’s loads of guys up here. Maybe you should try out churches in better demographic areas like St. johns(?), Linnton, Vancouver, Castle Rock ? … That’s unless you mean Portland, Maine .
If you’re back East, May God help you. The odds are not in your favor.

Blessings, sister. There is SO much out there a single woman can do to help the world!
