Insecurity alert

So my husband and I have been together since we were teenagers and over a year ago got married. Last year he had been talking to women on Snapchat as well as making online dating accounts. We addressed it and long story short I forgave him 🙄 but he went and deleted his social media accounts to work on our marriage and hasn't given me reason to doubt him again. He's definitely tried to make things work for the past half a year but recently he activated his Instagram again...

He didn't talk to me about getting it again which kind of bothered me. I haven't told him yet about how it makes me feel but also I feel like I shouldn't be this insecure about him having it? Idk I'm feeling super insecure and confused on how I'm feeling about him being on social media again... I hate that it makes me feel this way too😔 I know I sound super insecure and not trusting of him but I also can't deny the hurt I felt when he did mess up in the beginning of our marriage...😓
