Needing some advice


So in my last relationship I was cheated on for a while and lied to a lot so I picked up the habit of being super needy and paranoid about a lot because I was with someone for 3 years engaged and everything and I found out 90% of the relationship he was cheating on me so fast forward a year later and I’m in a new relationship and me being paranoid is causing problems but it’s so hard to kick I’m just beyond terrified to put my all into someone and have the same happen but I might lose my boyfriend now of almost a year because I’ve become horrible at giving him space because I did in my last relationship and that’s when I started getting cheated on and him not caring if I knew so I just I need some advice on how in the world to become less paranoid about everything
