Absolutely not okay. When you’re living with your boyfriend or girlfriend there are no days that are schedule for either one of you to have sleepover at other people’s home. This makes zero sense to me. The one way to have this be done is to live in separate homes. No one forced you to live together so if you are going to “play house” like the old folks would say you must abide by the rules. If you are feeling smothered by your mate then you need to speak up but no ma’am or sir are you allowed to just not come home. Who raised y’all? You have to understand that this is why you have to take living together seriously. Just because you love each other and already together all the time anyway, is not a reason to live together. That’s called infatuation. It fades trust me. It’s a magical feeling that overtakes you and makes you think you have unicorn powers over the abundance of love that you feel. It’s misleading.
The reality is that once you get in the house with the other person the real comes out. It’s a light bulb that is brighter than wattage you can purchase. I would say be clear about everything. How you live, the responsibilities of the upkeep of the home, how bills will be split and how you both plan to have a separate life together. Yes separate life. You even if you’re married don’t need to be joined at the hip. There should be mutual respect that is given at all times to one another in how you move and it sounds like this isn’t happening.
Have you both decided how things will work out if you two don’t work out? I know that love is powerful but love won’t stop the bills from having to be paid and we don’t need credit messed up cause love went left.
You need to have a talk to your boyfriend and go over the above and find out if he and you are ready to take on the whole cost of living together. This is why the old folks said don’t do it. They wasn’t trying to kill your vibe, they were trying to protect you from the ups and downs that you may not be emotionally ready for. Also what changes have taken place that both of you weren’t ready for? Is there more nagging and less communication? Both of you need to sit down and put things into perspective. Good luck but be clear-love is amazing but living together is costly in more ways than just your wallet.
