Long story but I need some advice

Okay so about 2 years ago I met my husband. I though but that he was the one for sure. We were so happy. And around May of last year I found out that I was pregnant. He moved to Germany a month later for work and we got married right before he left to Germany so we can get more benefits with his job for us and the baby. I didn’t move to Germany until September. So we were apart for about 3-4 months. During that time, I hung out with my best friend pretty much the entire time I was apart from my husband. I knew my friend for about the same time as I’ve known my husband but we’ve been so close since day 1. During the 3-4 month of separation, my friend and I became sooooo close. We fell in love with each other. We never did anything sexually but we did kiss a few times and each time was so intimate and so passionate. Also, my husband and I fought almost every single day about literally everything while we were separated. So idk if the arguing kinda pushed me onto my friend..? I’m just so confused because when I finally moved to Germany, it was the hardest thing I’ve ever had to do. I felt so heartbroken for leaving my friend to go be with my husband?!?!!? I love my husband because he gave me my baby boy but I cannot stop thinking about my friend. And when I left to go to Germany, my friend was so heartbroken as well and I was so emotional at the time because of the pregnancy hormones, I just don’t know what to do. I still miss and love my friend sooo so much. But I love my husband too. It is possible to love two people? The thing is, is that it’s a different kind of love. My best friend I think is the love of my life. I can’t get him out of my head and my husband, is great and I love him too but we’ve had our issues as well. He kinda likes to drink a lot and we get into arguments pretty much every time he drinks because he just treats me like crap then he ends up not remembering because he blacks out... but other than that, we are doing pretty well. I’m just so lost and confused. Idk what to do.
