My Life Situation as a Mentally Unstable Guy

I went to an event in the bayside area during the peak of summer, only to end up in the worst condition from heatstroke. The one who saved me was an older female doctor named Lisa, who lacks confidence in her appearance. Somehow, we ended up dating, and I even moved into her luxury apartment in a high-rise without much thought. Thus began a sweet, lovey-dovey (possibly dependent?) life full of steamy romance and playful adventures. Can this mentally unstable guy find happiness in his new relationship?
