A dialogue with your boyfriend's mother If you want to build, start the conversation by asking questions about it. It will also mean that you are not the only woman in his son's life. Ask your boyfriend to tell you interesting moments about his childhood.

When you're done meeting him, let him get to know you, because you're not an accessory his son carries around. Talking will also show that you respect him. Talk, ask questions, pretend to be interested, even if you're not. Most importantly, smile a lot.
To clear the table, wash the dishes Even if he doesn't let you, you can still offer to help. This will also sow the seeds of future daughter-in-law relationship. But definitely don't try to clear the table and wash the dishes without getting his permission. This can be seen as overstepping your bounds.
