I used to think I did. I used to believe that I could not function adequately on my own (and this was a learned belief through my momster - I was raised pretty much in the dark ages). I have to laugh, she once said to me, "But how are you going to catch a husband." O.O
That one still makes me SMH and that was decades ago - catch a husband, as though I should get my butterfly net out or an animal trap... for god's sake she really was a piece of work.
In any case, today? Absolutely not.
I learned the hard way that I need to be able to rely on myself first, including making my health and well being a priority, and then (if I wanted to) find companionship. Although I have learned this too late. I also have to add the caveat that I may be too cynical after what I have been through with my ex. Because of him, I doubt I will ever trust again - it is moot anyway, it is very unlikely I will be around much longer.
I have told friends who are looking for relationships - don't look to fall in love. It is nothing more than a chemical high in the brain that fades pretty quickly. Rather, if you really want companionship, fall in like and make sure to look for someone who is compatibile, in the sense that they have similar hobbies, beliefs, and life-style choices. That will help to mainain a relationship through the dark times, and there will be dark times - that is life.
But most of all, if you know you can rely on yourself, then should difficult or bad things happen when in a relationship, you know you can fall back on your own abilities to get through it and kick the other person to the curb if need be.
