Irritable, dislike my partner 28weeks

Hello!! I really hope that it's my hormones or I just need a good vent of anger but the last few weeks I really can't stand my partner at all. Everything he does irritates me and I just can't snap out of it. I cry at how I think I don't want him to be here with me and then try and convince myself that it's just my hormones but I don't know if it is. I don't feel like this towards anyone else just him!! Does anyone else feel like this or is it really just that I don't want to be with him?? Please help x
