Boyfriend advice

Before valentines my boyfriend and I took a break because I felt like all I do to him is treat him like an object (love him one second,,, ignore him the next). I took the break to heal and be better for him and for myself because our relationship was very toxic. I violated his trust as well as privacy when I looked at his Instagram messages with one of his close female friends. It hurt me when he said he didn’t think we’d last any longer and so a few days ago I told Him that we should break up. We didn’t and we are happy now but I can’t help but feel like we should still take one since the break only lasted a few days. I’ve known this man for over 7 years and I love him with all my heart and care for him dearly but I get so jealous sometimes that it ends up hurting him and he cries so badly that his bones lock up. He cares for me deeply and always reassured me that he loves me and only me and has no intention of cheating and I trust him so very much but I’ve seen many relationships (like my older sisters who’s lasted 11 years) end in cheating. I know I’m very insecure but I really need some advice on what to do since it’s so confusing half the time.
