Forgive me, I can't give you any advises since I never had a girlfriend (lol).
But I can tell you that don't search for romance but keep praying to the Father for guidance of Holy Spirit to choose right woman, right person for you.
Do you know one sight, one love?
I know a teacher who is currently taking a Ph.D course, never seen him again expect in Wal-Mart (everyone meets in Wal-Mart in our small town

)
His "love" was found during his university years (age around 20).
He had a girlfriend at the time when he met his wife.
At first sight, he said that he knew she was going to be his partner/wife/and friend for rest of his life.
He has a child and..maybe second coming? I don't know.
But I know that love can be found anywhere.
Also, many of Jesus's disciples traveled the world to spread the gospel of Christ, alone.
Without support of wife or children.
Some of disciples was never married either.
Also, Jesus never married (Apparently, some people are testing Jesus about this -_-..very unfortunate)
So perhaps, not marrying out be a plan for you?
But if you truly desire for woman or children, I guess you can pray for that too
Please, rely on God.
Relationship and Marriage is very loving gift from the Father to us.
I won't say don't rush it, but to just depend on God in this matter
God bless and may he find you a beautiful wife
