I need relationship advice😩

Been with my partner now for 4 years, and we have a 7 month old baby together. Ever since I fell pregnant I've started to doubt our relationship and lately it's gotten a lot worse, he's not a bad person. I just don't think I love him anymore, his presence annoys me. I've told him that I've thought about leaving him, but it's like he doesn't believe me. We argue a lot😒 and I can't be assed with it anymore, I'm bored and feel I'll be happier on my own. But the problem is... I own this house, and my partner doesn't have anywhere to go if I were to break up with him. I wouldn't want to make him homeless, my head is just so confused the now. I'm worried I make a mistake by leaving him, but I also I don't want to stay and be unhappy😭 I need advice, my head is messed...Â
