Slavs vs Indians matchup help

Feudal-I reached a bit earlier than my opponent.Went for a scout rush.He did as well.At the end of the exchange I lost 2 of my scouts and killed 2 of his vills.

I didn't lose any vils.

We reached castle at about the same time.Immediately went 3 tc. I started 2 stable knight production.I also started making 2 barracks Spears production and pikemen upgrades.Also got attack upgrades and knight defense upgrades.

He attacked with camels.I tried holding with knights and sent my pikes in after they got a decent number(which was quite quickly and I hardly lost knights).

As soon as I sent my pikes in he just left the fight and went into my eco.The pikes couldn't catch up and were getting whittled down by the Skirms and the knights were dying.

I tried mixing in monks but a few conversions were not enough.

I had to Garrison most of my eco and even lost a few vils.Tried counter attacking with knights but camels mopped em up.

Due to all the idle time my eco suffered and for the first time in the game I lost score lead.

Pikes were just running around uselessly and knights werent able to counter.

Then he sent mangonels and I knew it was over.

The opponent was also 1800s so his camel micro was pretty darn good.

I'm lost as to what I should've done.
