If you want a life partner, you don't view everyone you encounter as if they are the enemy trying to get something from you. You are either open to it, or not, but trying to manipulate the situation or assuming someone is out to trick you, well, you really will get what you are looking for.
I have two brothers, both past the age of desireability, if you will. One has had a series of long term relationships, married twice and is currently in another. In other words, he has had no difficulty in finding women who are interested in him, usually attractive and fit as well. He has always had a few extra pounds, is only 5ft 6in, and at this point, a bit balding and even more extra pounds. He has also been a single dad, sole custody, not a great saver, tho he does have a house. At this point, his good paying job shut down, before retirement kicked in, so he is working at another much lower income job, yet again, he managed to attract another woman into his life.
The main thing is, what he has that some seem to not have, is he is super nice, kind, generous, good natured, easy going, a gentleman and a gentle man, and he is (in spite of what his looks and income might tell us about him) a very confident man. He always has been, and that and a good sense of humour is what has always attracted attractive women, very loyal and in for the long term type women. Now a recent divorce had more to do with a clash of cultures (an evangelical woman from texas, brought into BC, not great for weather, not great for the God fearing Texan lol).
So when I see a few complaining about how women are this, and how they are that and why that means seeking out some poorer and more desperate type, I just think of all the men out there who don't have to play tricks and games in order to get into a long term relationship.
My other brother, a bit thinner and taller, has been with the same woman for over 30 years. First and last girlfriend. Another kind and gentle man, fwiw.
But neither of them have unrealistic expectations of what they should have as a mate, and they both understand what for better or worse really means.
