Getting older and very indescisive in love life

I’ve just turned 33 and I haven’t brought anyone home to meet my parents or family ever. I date pretty consistently. Things last about 3-6 months typically and then when things are about to get more serious I bolt....every time. I am seeing someone currently and am trying to give it some more time (try a little harder to make it work) but it just doesn’t feel right. Thoughts? I’m clearly a commitment phobe but I really really don’t want to be like this forever!
