Gosh you sound like you have a lot on your mind. Firstly relax…you are young you have time. There is no hurry. The process of finding out God’s call is slow and gentle… like a breeze blowing. It is not going to be one minute you don’t know the next you do. It’ll be subtle suggestions …most likely.
I don’t know what country you are in but I am a retired Police officer from the UK if you want any inside info on what the career is really like. Oh I’m retired due to ill health so I am not old an you won’t hear lot’s of… in my day …etc.

I retired in Dec 2013. But that’s not too relevant if you are in US. I haven’t read every word above so sorry if you say, I am not good with scrolling
Did you know that it’s very common for people being called to priesthood to experience a feeling like a call to marriage as well? the two are closer than you think, they are both fathers, the feeling is very similar.
I saw you didn’t manage to get a spiritual director. Have you tried getting a book on discerning a vocation? in the meantime. I got one from CTS (Catholic truth society) and found it immensely helpful for me (of course my option were much more limited than yours) . If you go through the steps in that or another book and contact your diocese vocations director for information. You can receive guidance without any commitment to a specific direction. Also praying is immensely helpful, the rosary and adoration especially. Work really hard on improving your spiritual life and believe me the rest will fall into place in God’s own time.
As for dating, don’t push it, let God lead you if it’s meant to be… He will show you how, where, when and who. It would be better to start out making friends and see where things go from there.
