This question is for Catholics?

I am very sad. Not completely sad for I feel joyful because Jesus Christ lives in me, but sad meaning "not happy." I have always wanted to get married. I know I am still young, but everyone around me is dating and I have never had that. I am 21 and live with my mom. I am starting to think maybe the Lord wants me to be a nun... I have had three attempts at relationships and all of them failed. At first I wrote a guy whom I really liked at some point and he wrote me back, and he was all for communicating, but then, I don't know what it was, perhaps I said something wrong... he just disappeared out of my life and I never even got to spend time with him... It was weird. The second time I asked someone out and that someone rejected me. I was embarred, but quickly got over it. And the third time, thank God for the Internet, I really liked an Orthodox priest, and the reason why I say "Thank God for the Internet," is because it was over the Internet that I had found out that Orthodox priests can only marry prior to ordination and not after... A nice joke would it be if I were to really fall in love with that person.... I still like him, but I am working on conquering those feelings... I am such a fool when it comes to relationships... Understandably so, I have never dated anyone, hence I don't have much experience.... Maybe I am not attractive, I don't know... I have always dreamed of marriage and the possibility of becoming a nun and shutting myself from the world appears to me somewhat hideous! On the other hand, living with my mom is very tiresome... I don't have any other relatives and each time I imagine that I'll have to spend the rest of my life with my mother I want to die... figuratively speaking. I know some of you will say, "You are still young, 21 is very young etc." Well, I know all that, but the best time for a girl to marry both physiologically and psychologically is between the ages of 21 and 25. Now, my husband will have to be godly. Unfortunately there aren't any godly men that I know of where I live, except the priests... who can't marry, and seminarians, who are too young... I would only marry someone who is 10-15 years older than me, and those two conditions are the most important ones I have - godliness and the age difference. It is pitiful, really... I have spoken about all of this to a priest, and I have prayed about it, but I still feel this loneliness... "Jesus is all you need," you will say... Fine. The words will not solve the issue I am having, so, please spare me the lecture... It hurts enough without moralizing... I thought may be some of you could, perhaps, pray for me... I so want to have a family, I want to have a husband with whom I would share my faith, a relationship that would glorify God, and kids that I could teach what is most important to me and bring them up according to the Lord's plan... Why cannot I have that?! Why?!? Can you offer me some perspective? It is hard for me to be alone, especially taking into account the fact that I do not have a lot of friends...
