My relationship falling apart

I’m really sad my relationship is falling apart I really care about my bf and everything but I’m tired of him lying all the time. I wish we can fix things we been together for 2 years almost 3 and I was pregnant with his child and it’s so hard to let go completely I was mybe thinking of moving in soon mybe that would be a good idea and we can try to fix things and argue less or should I end things with him. Idk I need some advice.
