relationship advice

I’ve been talking to this guy for about 8 months now and around 5 months ago we got serious serious, relationship wise. It wasn’t till 2 weeks ago when he actually asked in a big way and everything even though we acted like a couple from a while back. He’s the best. Always spoiling me, prioritizing me, always wanting to see me. A dream man. However, when we argue or fight he always brings up that he’s the only one putting in effort and that he thinks I need a “break”. My mental health isn’t at its best so I know Im not the best to deal with but I always tell him I don’t need any sort of break. Is it bad that I overthink when he tells me I need a break ?
