As some who is not quite 22, you seem to have time on your side? Why the rush? So many early 20-somethings value their new freedom and are anything but anxious to pair up, let alone to get married and start a family.
Probably one of the biggest turn-offs to a legitimate prospective BF is the woman's projecting a whole lot of need, which he is then expected to fill. This is a heavy burden to place on another person. The Unavailables have few worries about getting roped in, and the Unattacheds might head for the hills if they think you want to get too serious too soon.
Try being the happiest, best single you know how to be, and to relax around your single status. Once you can do this sincerely and shed your neediness, you will become much more attractive to Mr. Right.
Astrologically transiting Neptune has been opposing your natal sun. This can be a very trying time of low energy and self-doubt. What you believed to be real and true about yourself seems like it was all a big illusion, after all. In your case the situation is being exacerbated by Neptune's pairing-up with the planetoid Chiron ("where it hurts") so you are probably feeling some emotional pain keenly at this time. A good use of this transit, however, is to develop a healthy sense of spirituality-- have faith in the universe to support you. Just try to avoid too much alcohol and drugs during this period, as you will probably be extra-vulnerable to them.
Neptune in the 11th house of friendships (such as co-workers) could be Mr. Wrong, but Neptune shows more generally, in a stressful aspect, where we are apt to be overly idealistic at one time, and disillusioned at another.
With Venus (your 7th house ruler) conjunct your sun, a loving relationship is very important to you. But the first lesson of Venus is learning to love yourself.
The year ahead does look trying in the relationship department, with transiting Saturn (Dr. No) sitting on the cusp of your 7th house of relationships. (Sometimes Saturn on the cusp or in the 7th house can indicate a relationship with an older person, or someone who seems exceptionally mature (Saturnine) in some way, however.) Saturn always teaches self-sufficiency and deferred gratification, however, so it might just be asking you to work on your independent solo skills.
Sometimes people (oh, like my daughter and my niece) don't meet the right guy till later in life. This can be hard to contemplate in your early 20s, but definitely worth the wait if it happens.
