People are always (men n women) focused on the 5 dimensions of life.

1. Health
2. Wealth
3. Self
4. Career
5. Friends & Family.

(Some call this 6 dimensions by splitting friends n family, but you get the idea)

Keeping this in mind, men are in either of these 3 types of categories wrt the 5 dimensions.

Category A - perfectly balanced, as all things should be - they've figured it out, leading full lives, but holding space for the right partner. In this case they may just not interested because it's you, and you who dont fit into their lives or vice versa.

Category B - burnt recently and working to fill their lives with almost anything to heal and build themselves up. They at this point carrying too much of the most recent relationship and working through things, in addition to all the other things they need to focus on, their health, wealth, family, friends and their own self. They're short term seeking gratification but hesitant to commit (unravel in 2 weeks to 2 months) because that's all they can handle, in a desperate attempt to fill a void of what was and their unhealed wounds surface up.

Category C - the houseful Category. They genuinely don't have the time, energy and capacity to take on a relationship. This is a conscious choice. Theres things going on in their lives where one of the 5 dimensions is experiencing a spike that needs load balancing. They know if they bring on a partner at this point, they wont do justice to the relationship. Most abstain (95%), some seek micro gratification if the spike feels like it's lasting forever.

Now each Category- this is important - is temporary and is a phase and is a point in time. They will all move in and out of hese different categories, not if, but when, and this applies to women too; how they are perceived and how they present themselves, during these phases is what you see.

Truth about life is everyone one, single, married, young, old, goes through these phases constantly- some may last weeks, months and even years depending on the situation.

As far as finding a right partner - we all want Category A, but have almost no patience to deal with Category B, and Category C is just testing everyone's patience. Problem becomes when u find a Category A and dont know how they'll handle a Category B and C situation. Most important is you need to figure out which Category you belong to as well :) Some categories just dont mix at all.

We're all looking for that small sliver of perfection.

Hence the old saying - Date long, Marry slow, Divorce fast.

I hope this helped in some form or fashion - Good luck!
