male cat not accepting female cat

I have an older male indoor/outdoor cat he is a tabby
And i took in a female calico cat that is a little bit younger and now my older male
Stays gone more and is hesitant to come in the house
Ever since I took her in

I never seen any negative signs such as growling/
Hissing biting etc. He just shyed away from her the
Day I brought her in and hasn't been coming in as he usually
Does since I took her in

I don't know if he's feeling jealous or hurt

And I also don't know how to help the situation
All the cats I've ever had has always gotten along

I've never experienced a male not liking a female

Females are more dominant by nature.  Because he is obviously an outdoor cat and she indoor(?) he may now view it as hers and is staying away because that is cat dynamics.  If you want him to come back, he needs to be indoors and a proper introduction needs to be made.  However, because females are more dominant, and she was technically there first, she will be seen as the alpha. 

Actually he was here before her she has only been with us for two days
He's been my cat for a few months now and before he was our neighbor
Said he was a local stray for years.

But since I took the female in the males attitude changed
He dosent want to stay in like he usually does... he eats and leaves

Last night I saw some friction between the two
They growled at each other and glared at each other
With their ears back and both of their heads down .. it
Lasted for a minute and then the two went their separate ways
In different parts of the house

That's normal.  He'll come around less and less unless you keep him in and do a proper introduction.  Again though, females are more dominant by nature so she will be the alpha. 

I call it establishing the pecking order

You have to let her be the alpha. Keep them both inside for a month, do a proper introduction from scratch and whenever you come across them in the same room, establish her superiority by ALWAYS greeting and petting her first, feeding her first, etc. But when it's his turn, show him a lot of affection and attention so he knows he is still loved and welcome in your home. Maybe start a habit of handing out treats to both of them every evening so he'll look forward to coming home each day.

I agree about doing an introduction. And, yes, that will mean keeping both cats indoor only for awhile. Otherwise, your male will likely spend less time at home, or it will take much longer for him to accept the new kitty and return back to a normal routine.

Proper introductions are a must. Keep her confined to one area and let him have the rest of the house (after all, he was there first, it is his domain.) Start with scent swapping (using a blanket or towel...let her have it first for a few days and get her scent on it, then put it in an area he frequents and see how he reacts. The goal is for both cats to tub their scent on the blanket and, therefore, mix their scents together.)

I disagree with the others that the female must be treated as the dominante cat. Yes, many females have this trait; BUT, I have also known (and have owned) females that are NOT the dominate cat. The cats will essentially have to figure out the pecking order.

well in the other night after everyone went to bed he came in to eat and I refused to let him out for a while
After he ate and settled down I picked him up and put my male cat in my lap and sat and petted him for a while
Like we normally would do.. after a while of petting my male cat he started purring and layed down on the couch
Next to my female cat that was laying on the arm of the couch to my surprise.. so the too have made progress
But still keep their distance .. that's the update
