Yeah I agree with what @Viswamitra has advised. The problem is you are running away from her all the time. Every night after dinner maybe when all are relaxing just talk to her for half hour or so. Casual chitchat, oh today was so busy, next week I have deadlines how are you? Stupid maid etc. Make this a regular habit. Then if she disturbs you during the day smile and quickly say ‘let’s talk tonight/later. I’m really busy right now.’ Gradually let that night half hour be the main point of interaction and she’ll stop barging in on you at other times.
