Did my being emotionally immature add/contribute to my boyfriend committing suicide??

I am 32, who up until Feb. was dating a younger man, 25. We had been together for 2 1/2 years, but we definately had our battles in that time. He came from an abusive childhood & had been abusing drugs for at least 4 years prior to me meeting him. I had been single for 8 months & was excited to meet someone. (My past relationships consisted of me always getting jealous or fighting about something stupid. If not that, I would get bored & think the "gr was greener". Looking back, there is a repetitive pattern of me holding in my feelings, scared of getting hurt, or left & then I start getting jealous & then end up ruining a perfectly great relationship. My late boyfriend looked up to me for support w/him getting over addiction & really relied too much on me & my strenghth. It was too much & I fell back into my old ways - jealousy, bitchy, fighting, dumb girl stuff. He was already immature & I think the fact that his only attempt at love was tainted added to his depression & suicide??
