While all the time you always attempt to read him are just a shot in the dark, you can actually have signs he is in love to give you idea to what his heart is really telling you in the first place.
See below for some clues that he is in love with you.
Top 1 - He reciprocates the great chemistry you two have.
To start, you can never have a relationship with someone you have not established a connection with let alone think that you are in love.
Same is true with your guy.
If he reciprocates the chemistry you both have with at least the same level, it could be your sign that he is indeed in love with you.
It is a great thing to consider when you both know what to do even before words are being said.
It is also a great sign when you both are comfortable even without words are being said.
Top 2 - He does not find your idiosyncrasy something that you need to change.
When he finds out about your weird habits, he finds it charming and cute instead of something that you need to stop doing.
In other words, he accepts everything about you including the little things that people may find strange and irksome.
Your obsessive compulsive tendencies do not really bother him the least.
You do things your own way and he follows with the way you do it and dare not try to contradict you in whatever way.
He can't really explain in coherent words if you ask him about it.
Top 3 - He shows he cares about you.
You can say that one of the signs he is in love with you is the way he wants to know everything about you.
He does not demand any information directly from you but will try to bring them all out from you when you are comfortable.
In one of your conversations, he may want to know where you spent your childhood or ask you what you think about a certain matter.
Everything about you matters to him.
Above of it all, when he can't seem to explain in the full context or finds it hard to tell you just why he does things he does, it is one of the great signs he is in love with you.
