What is Important in a Relationship
What I have noticed is that many people create their own loneliness either by not being mindful of what they are looking for in a partner or what they can offer to a partner.
Many people think that love just "happens," to them ("you'll know you're in love when it happens to you," as my dear Mother used to say, may God rest her soul).
Here's an example, based on my own life, and I recommend people to make such a list so they can be more aware of their needs:
What I Can Bring To The Table
Supportive personality
Fiscally responsible
Kind
Faithful
Committed
Monogamous
Understanding
Not demanding
Well-mannered
Low maintenance
Wide variety of interests
Not materialistic
Simple lifestyle
Not looking for a "Sugar Mama"
What My Needs Are
Supportive personality
No drama
No smoking
No drugging
No heavy drinking
Faithful
Committed
Monogamous
Must understand I am on a budget
Open to Living Apart Together (LAT)
Am allergic to pets/tobacco smoke
My partner must be clean and dress neatly
My partner must have the same degree of femininity (mid-butch) as me, or more feminine
Basically, I could be with a wide range of women, rather than a "type," but they have to have an excellent CHARACTER.
This is an example of writing it all down, instead of keeping it all in your head, so that you will have a more clear idea of what you can offer others in a relationship and what is important to you in a relationship.
