Anxiety

I cant sleep at night thinking about the times my husband cheated on me before our marriage and how possibly it could happen again. We just got married 4 mos ago. And a month before the wedding, i caught a message on his phone. He was asking a random girl for sex. Hindi daw natuloy ung "do" sabi nya. Pero dapat di talaga matutuloy ung kasal kasi ayoko na. But i am pregnant and we're already 90% on the preparation. He showed regret and guilt, he continued on the prep without my cooperation kasi ayoko na talaga. So natuloy parin ung wedding and now im feeling stuck with my decision. I know he loves me and I love him so much but i feel like pinaparusahan ko lang sarili ko. 4mos married and 8 mos pregnant here ?
