He just gone

My boyfriend and I’m pregnant with his baby, 15 weeks, been with him 9 years, I don’t trust him one little bit, he’s 17 years older than I’m 31, anyway he leaves early for work dosent come home till 9 on the night time, he just walked in and I said I’m sick of this and I think he’s cheating, he said he was with his mom and I said just get out and leave me alone, he’s gone now, I can’t keep going through this stress every day, he cheated a few months ago and now I do t trust him one tiny bit, wish I was dead rite now feel like shit
