I just need to vent about my relationship for a moment. I’m a 32-year-old female engaged to a 31-year-old male.

I'm honestly not sure where to begin, so I’ll start from the top. I’ve been with my fiancé for seven years, and we got engaged last August. Over the past year, he's started to pick fights with me over the smallest things. For instance, just yesterday, he picked me up from work (since my car is in the shop), and I was talking about wanting to go to the beach and what it would cost to split. He seemed on board and said he could cover his half in a few weeks. Then, I mentioned my new building and how we need to get insulation this weekend, something I’ve been bringing up for weeks. He replied that his friends were coming over Saturday, so why couldn't we go get it today? I explained that I didn’t want the insulation to just sit around for weeks because, let's be honest, if his friends are coming, it’s unlikely anything will get done. I suggested we wait another weekend instead, and he exploded, insisting that his friends would help him. I told him he couldn't rely on them for that and that waiting made more sense. What escalated into a huge argument was really unnecessary. If I’m paying for this insulation, why couldn’t he just say, "Let's go whenever you're ready to install it"? I want it in place, not just sitting there. To me, the whole argument felt absurd. He then said he was done and couldn’t continue living a life where we argue daily, especially when he comes home after a good day at work dreading our time together. As someone who’s pretty sensitive, hearing him say he was done really stung, and I know I won't forget it. I’m not sure why I’m even sharing this, but I need some perspective. I love him deeply and have supported him through some tough times, but the constant fighting over trivial things is exhausting and honestly makes me feel worthless. I realize now why he's often nonchalant when I discuss wedding planning, dismissing it as too expensive. Our entire wedding is under $10k, and I agreed to pay half, so it’s really not as costly as most weddings. I’m just feeling completely lost right now.
