ANSWER:

Both of you are right. 

It’s sunnah to pray again (with the intention of voluntary prayer) if he already prayed and congregation is going on because people might think wrong about him. 

For women it’s not obligatory to pray in Masjid in congregation so what you did was OK for you.

Brother, me and my husband prayed asar prayer on time at home and after that we went to a nikah at mosque. My husband prayed asar prayer again with the congregation because it looks odds not to pray but I prayed tahiatul masjid and sat … which one is right?

Even though I try avoiding, still at times owing to unforseen circumstances (once in a month or so) I get stuck in traffic jams in my city which result in me missing the congregation. So, what under such circumstances is better for me especially if there is plenty of time left; to pray alone as soon as I find a Masijd or to lead a prayer in congregation at home with my wife behind me?
