I feel like he is losing interest but many of his actions say otherwise?

You do nothing! Seriously, you can’t expect a man to constantly romance woo and sweep you off your feet forever. The initial phase is based off infatuation but those are chemically induced feelings. If you aren’t able to segue into a calmer/stable adult relationship where you can spend time apart and feel no differently than when together then you’re missing an integral element.

A man shouldn’t be the center of your world. That’s too much pressure to put on someone’s shoulder’s and need to learn how to be in an “interdependent relationship” (look it up.) If my SO surprised me with KFC when super tired I would be very appreciative of his efforts. I sounds like you have a “half glass is full” mentality by picking everything apart based on a hypothetical conclusion you’ve built up in your own mind.

He could be picking up on your negative vibes? What you put out there is what you get back. Try to alter your mindset by believing your relationship is going smoothly by being the un-anxious, calm, easygoing, secure and confident woman :o)
