Had a wierd experience today

Was going somewhere near in the Hosur road area and saw a dude trying to get hold of a girl while she was just trying to avoid him. I got suspicious and stopped the bike and asked him "hey, what's this? The dude was on a bike and i thot that i saw the girl with a hand support(i might be wrong) which people wear when it gets fractured. The dude was straight up hostile towards me.."Hey who are you? This is my wife". The girl didn't say shit. So i assumed OK. and i went ahead but i was still not satisfied. I went and little ahead but then i reversed and on returning i saw the girl had gone way ahead and the bike dude was now talking to someone on phone when i noticed that his shitty bike didn't had any plates. Then he stormed off behind that girl and i also pursued. This time when he saw me he gave me a look from the other side of road and came onto me like he was going to hit me but i also showed the same temper and didn't back out. Then there was a heated exchange between us, threats were given by him, No violence , No profanity from both sides.

My Questions:

1. I have hard time believing she was her wife. They were both looking like chapri but i didnt see any signs that you see indian wife has(hindu or muslim whatever) like burqa, Bangles etc.

2. The dude seemed damn suspicious to me. His demeanor was very violent.

Concern:

I go through that route frequently and with my family. Should i be worried that the dude has singled me out? Because the area often becomes pretty lonely at night and i travel in night also.
