1. ENGAGING IN OTHER ACTIVITIES THAT EXEMPT YOU
At times your man can decide to hang out with his friends play around or just have fun but it becomes alarming when it occurs too often. This happening more than 3 times a week is a sure sign he either unhappy or just simply prefers their company especially when it wasn't the case in past years.
Situations when you say little things that wouldn't normally induce irritation or annoyance and he sparks up like a fuse box is a sure sign he isn't happy. Yes as a human he gets angry over one or two things but more often than not deserves a meeting or talk time or questioning of some sort. The earlier the better.
3. NONCHALLANT OR INDIFFERENT ATTITUDE
In a good relationship , caring is of utmost importance. When he suddenly doesn't care about decisions you make on important issues or simply pushes aside vital topics that needs attention then he isn't happy.
4. BODY LANGUAGE
This is the easiest clue to know if he is happy or not even without uttering a word. Back then he would prefer cuddling than reading a newspaper alone or would kiss/peck you whenever he is in close proximity or creates body contact whenever possible and then he stops all these all of a sudden then you two need to sit and talk about it. Be careful though you shouldn't judge after a day or two because it might be due to stress at work or something related.
5. DISMISSING YOUR ARGUMENTS TOO OFTEN
70% of men would prefer watching an old man attempt somersaulting or a child play dress up than sit through an argument with their partner. This is true because only few of us women would actually admit we are wrong. But situations when he completely dismisses or shuts up your opinion on a topic or uses phrases like "We have been through this before"then walks out on the argument more often than not it might be a sign he isn't happy.
6. HE KNOWS WAY TOO MUCH ABOUT HIS COLLEAGUE AT WORK
He tells you Maria just bought a new nice dress and you like "That's lovely" and you also know few days ago she suffered from diarrhea. Last week she broke up with her boyfriend,few hours back she had to send her younger brother 50 dollars for school!!! That's like a whole summary of her month. But hey he is allowed to have a female friend but knowing tiny personal details is quite worth raising an eyebrow for. This just simply means he is seeking attention outside which isn't healthy.
7. HE'S SKYDIVING WITH HIS FRIENDS
This might sound alil bit off but trust me it's worth noting. Not necessarily applying to just skydiving as an activity but also other things you as his partner can do with him. It's possible you are quite rigid when it comes to trying out new things and would rather prefer sleeping all weekend. This will overtime make him seek more fun from his friends and spend lesser time with you which still boils down to unhappiness.
8. SEX IS A DUTY
As a couple you both know how you prefer your sexual activities done. If you do a lot of fore play normally and now he just undresses and resumes penetration with little or no details or interests then you both need to talk. Sex is what most men enjoy and a very good way to express how they feel. If it becomes straight to the point or boring in comparison to the usual then it's a sign something is amiss.
9. HE DOES NOT BOTHER BRINGING UP THINGS THAT BOTHER HiM
After a long day at work he would normally tell you how it went or every other day he gives you a breakdown of fresh new thoughts that keeps him awake at night and all of a sudden he stops and dismisses your queries when you see him gloomy then he is definitely not happy with you.
10. DOES NOT BOTHER RETURNING YOUR CALLS OR TEXT RIGHT AWAY
Speaking from experience my partner returns my calls or texts literally minutes after I send them. Situations when otherwise occurs and happens more often than not then something is wrong. Returning your calls is a way of knowing he's got you on his mind no matter how busy his schedule is.
So there you have it. These are my 10 physical clues to know when your partner isn't happy in your relationship. There are thousands of others but it all boils down to knowing your man's actual personality before making a good judgment and talking steps to alleviate it.
Best of luck.
