Imagine if your boyfriend doesn't exist and had never existed. What would be the very best thing for you to do Monday to Thursday between 5.30 PM and your going to bed time?
Do work to build up your own ethical business?
Get training to help you build up a successful business?
Go out and socialise with friends?
Go and do activities outside the home? Linked to some passion or hobby of yours, such as playing a sport, going to concerts, comedy clubs, cinema etc?
Cook delicious, healthy, nutritious meals?
Learn how to cook delicious nutritious healthy meals?
Do some hobby or passion based at your home? Work on your model railway in the attic? Watch Eastenders? Read Lord of the Rings?
Do some chore or work at home? Redecorate, renovate the bathroom, service and repair your car?
Something else worthwhile because it's rewarding or enjoyable or urgent and important?
Some combination of the above?
This is an effective 2 pronged approach.
1 Doing something positive with your time will increase your boyfriend's attraction towards you. How much will depend. It's difficult to say as he's taking you for granted and is so addicted to his gaming and anime. So you do have an uphill battle here. What you will have done by maximising your evening time is to make yourself into a significantly more attractive person. Because it's not just you doing a load more rewarding / enjoyable stuff than you used to, it's the underlying mentality that you will have in doing so.
The fear of missing out can be a strong motivator. If your boyfriend fears that he's missing out, he might get off that couch of his.
2 The general quality of your life will improve by you making good decisions on what you do with your mid-week evening time.
Keep asking yourself "What else?" What else could you be doing that's better than what you're doing right now. If it's something better: do that.
