Think this way and see what answer you reach
If you get so uncomfortable now, how will you handle it if it actually escalates in future? And won't you feel miserable then for ignoring your own feeling?
Of course, there is a possibility of you overthinking too. But some of the things you stated do sound concerning...like him talking about your ancestral property or him not professional at work place. Also one's colleagues get to see a side of his/her personality that he/she always want to gloss in front of partner. So even if he is committed to you and love you dearly, think about if you will be able to deal with his remaining part of personality.
