I need some advice

I seriously need to work on my jealousy I am so jealous, so insecure but then I'm not like I really don't know because I'm confident with myself but jealous because I know what kind of girls are out there for my bf if that makes sense I have big trust issues he's never cheated on me but he has lied about little stuff and I see it as if you lie about somthing little you sure in the hell would lie about somthing big but the trust issues fall back from when I was little my dad cheated on my mom and my mom took me to the place he was to see it for my self so ever since then I feel like all guys are cheaters, I am also so controlling because I'm scared to get cheated on.... I'm thinking about when I start working maby get a life coach, maby work out and get my body right to be a lil bit more confident with my self, or do y'all think it's best if I tell him let's take a break so I can work on my self ?😭🤦🏻‍♀️ we have been together for 7 years going on 8 and have a 5 year old son so that's somthing else I have to think about !
