Maybe divorce ?

So back in November and December me and my husband had a really low spot in our relationship and marriage but we both agreed to try to work on it and we both were. Everything was going good but you know some past relationship issues kind of got me in a weird spot and made me insecure.He does YouTube and Instagram for fishing stuff and aquarium stuff and I support him 110% but you know trying to network with other Instagram or’s and Youtubers you know he was liking other pictures as in girls pictures which he was 100% straight up about it but I just got very insecure for no reason and now we got in a big fight we were both drinking a lot of alcohol and you know just blew things out of proportion and honestly I blacked out when we were drinking.He still wants to buy a house together and still coparents and everything living under the same household but he said he just needed time to see if you wants to fix our marriage and it’s just like I feel so guilty what should I do to help get my marriage back on track. Please ladies give me some advice
