If you want your girlfriend all to yourself, my advice to you is to take her out away from her home. If you want to hang out at home and eat a home cooked meal — make it at your house, not hers. Her roommate is part of the landscape there. It’s unreasonable for you to expect her to not invite him to the table if you’re eating at her house. I’m not saying it’s wrong, but it is unreasonable to expect her to change her behavior.
Take her out for meals, movies, walks in the park, beach days, etc. Take her away for weekends. Invite her to your house, and make your house the home base for the two of you.
I’ve written this book called Romantic Date Ideas that you can buy by clicking on the link above, Dating Advice Books. It will help you come up with lots of date ideas, places, and themes. You’ll love it, and it will help you make a relationship with your girlfriend out of her house.
Instead of getting into fights about her mentioning her roommate or her ex-boyfriend, focus on the two of you. If she mentions her roommate, just don’t respond and keep the focus on the fun and romance the two of you are having. Eventually, she’ll focus on you, only.
