HELP ❤️

Cece 🖤 • 😍
So me and my boyfriend have only been together for a couple of months (Since February) 
But I feel like everything is changing 😩 
Feel like I'm the only one that puts effort into the relationship. When we have arguments I'm always the one getting blamed (Everything is always my fault even when it's not). Feel like he's already done with my shit and is sick of me . I have changed the way I act to suit his lifestyle but he hasn't done anything to try to suit mine. 
I don't know am I overthinking it ? 
Please comment some advice 🖤
