I am not the best to answer this because I have never married, nor been able to.
I resigned myself to the fact that God may have chosen me to be single, but others
, on here, kind of convinced me that the problem is myself. But that is beside the point of this reply top you.
I am all for online meeting as I know people who did and are very happy.
But while you \are doing your search in addition to putting yourself out there in social settings I would suggest you do one thing to broaden you interactions with young women.
Join a well rounded pen pal site. You will not likely find a mate through there but
if you establish a couple of good pen pal women friends you can fine tune and hone your communication skills with them.
I will warn you though that not everyone you contact will reply, or if they do 99% will only reply once or twice. Do not give up.
You can post your own ad or just reply to those that catch your eye.
I have made some great friends doing this, inclusive of one Bible study with a pastor.... and also 2 other pastors... and a cyber stalker, and a pedophile, and some real scummy people, and sone truly wonderful ones....
In other words.... a real mixed bag, but had truly made me a better person to be able to talk with men.
I prefer pen pals now dot com because you do not need to show a picture and you do not fill out all the profile stuff. You can look for the age group you want and you can contact people without even putting anything there for yourself.
I will say that good for you in completing your degree. A low income job is not bad at your age... just be sure that when you are discussing your dreams you impress on her that you have a loftier goal once you graduate....
