Does this mean he likes mee? GUYS please! :)?

weve been talking for about 3 years as just mates but lately weve been getting a bit more flirty and stuff. and tonight he came to see me in work, an he robbed my phone an we was play wrestling so i could get it backk off him, then there was about 5 or 6 empty chairs saround the group he came in with an he decided to squeeze onto my chair what i was already sittin on. is he just bein flirty orr does he actuallly like meee?
