Im so scared of falling deeper in love with my boyfriend?

i sat and talked to my phsycoitrist(worng spelling) but she figures that since my grandma ped and my real mom ped it made me afraid to love. and she figures i love my boyfriend alot and my subconscious thoughts that are negative in my head are telling me to leave my boyfriend .. just weird things that i would never say. he;s perfect he loves me unconditionally. i love him the same. i broke up with him two times and when i did it i regretted it! this feeling goes away and then comes back. i hate it and i want it gone what do i do?
