I am single and looking too. I would suggest reading a book by Henry Cloud called How to Get a Date Worth Keeping. Basically the book is challenging the idea that it is 100% up to God that we find a spouse. What i mean by that is we can't sit at home, eat lunch alone at work, spend lots of time alone and do nothing to meet men (or women). If we do that, expecting someone to walk into our lives, our only prospects will be the UPS person and the mail person. Sure if we are walking with God, he will put that special someone in our life, but we have to do out part by being as social and as open and welcoming as we can.
I am rereading it now and find it encouraging.
There is also the idea that we need to be inviting and approachable. Some people don't understand this but it can be illustrated this way: Ever known people who ALWAYS seem to have a crowd around them...these people have many friends. Their body language, their personality and I am sure a bunch of other stuff that I cannot identify, send messages to others that invite them in. You don't have to be the life of the party to attract others, you just have to be open, inviting and welcoming of others. The most obvious thing these people have is right on their face: they genuinely smile and look at others in the eye.
