Dead giveaways:
- Selflessness - reason - he values you more than himself.
- Gifts - reason - friends don't usually do this and it is love if nothing is expected (i.e. sex).
- Surprises - reason - he wants to stand out and impress you for the long term.
- Alone time - reason - friends don't usually seek exclusive time.
- He flat out says it - if you believe him.
Ambiguous:
- Eye contact - reason - he could just be infatuated, same with sex and cuddling.
- Wants to spend a lot of time with you - reason - he could just value your friendship
- Compliments you a lot - reasons - obsequiousness, envy, low self esteem.
- Interest increases with time - this is also typical of many friendships.
- Romance - reason - watch out for the players. It could be love in combo with the above list.
- Exclusivity - reason - like above some guys like multiple exclusive people under their thumb, and over their beds, but like the rest of the signs in this list, it is plausibly also genuine love.
