PA28 pilot reported an near midair collision with a learjet on departure from bdr.

Narrative:

I was climbing during a straight-out departure from runway 29 at bridgeport airport. I was at 2900 feet MSL; heading 290 degrees. I looked out my left window during a scan for traffic; and saw a learjet at about 150 feet away; at my altitude; also heading in a westerly direction; in a slight left bank.I am quite certain this learjet had also just departed bridgeport soon after I had; because I remember seeing the aircraft on the ground at bridgeport waiting for takeoff clearance as I was taking off. I assume; but do not know for certain; that the lear had also requested a straight-out departure from runway 29; and had overtaken me because of his higher speed. I assume the lear pilot may have seen me and therefore was banking left to avoid my aircraft; but I also don't know if that is true. It may have been luck that he had banked when he did; or I believe his aircraft may have collided with mine.I believe the only way to have avoided this near-miss was for the tower not to have allowed the lear to perform a straight-out departure so soon after a slower aircraft (my aircraft) had departed on a straight-out departure. Again; I do not know for sure if the learjet had made a straight-out departure; or if he had come so close behind me during maneuvers after some other type of departure. All I know for sure is he came from behind and was very close when I finally saw him on my left.

Title: PA28 pilot reported an NMAC with a Learjet on departure from BDR.

Narrative: I was climbing during a straight-out departure from runway 29 at Bridgeport Airport. I was at 2900 feet MSL; heading 290 degrees.
