Overall, I think you lost the game with moves 42-62. Here are some comments (I'm a little tired, so take them with a grain of salt).

;B[id]LB[hd:A]C[Also just FYI, A is usually better shape for black here.]

;B[lq]
;W[qq]C[A reasonable choice for white, I think.]
;B[pq]
;W[qp]
;B[pr]
;W[qr]C[Black's play at Q2 is not normal (usually it is at Q5). For white, I like R5 better than R2. In part, this is because white would be pushing ahead, rather than from behind. Your move does set up a trick play, though: if black now plays R5 you can cut at Q5 and capture one side or the other.]
;B[np]
;W[bp]TR[qp][qq][qr]C[A big move to be sure, but I would hesitate to leave the three marked stones alone--you have some potential territory on the right, and black can severaly limit and push it down. Just a thought.]
;B[cq]
;W[ck]
;B[qn]
;W[iq]C[I know magicwand (who is much stronger than I) said this invasion was good. I don't disagree, except I think you need to respond on the lower right or your corner might die.]

;B[jr]
;W[lp]LB[jo:A]C[Definitely should push at L2 first - black has to respond, and it looks like that is your intent behind your light knight's move at A.]
;B[kr]
;W[hn]LB[if:B][nf:A]C[If you're going to run out, I say run directly toward the center, which would indirectly help you reduce the top. A and B are some reduction points I would consider.]
;B[qk]
;W[pd]C[I think black can ignore this and play at P17 - Q15 is not important (if you capture, you get some strength, but there isn't much opportunity to use it now).]
;B[oe]
;W[oc]
;B[nc]
;W[ob]
;B[nb]C[Here, I feel like you helped black solidify some of his territory and make him stronger, which makes the entire top side difficult to reduce. True, you solidified some of your corner territory as well, but black gained more - especially considering that he gained both territory AND influence.]
;W[qb]
;B[ci]
;W[eh]TR[cf][eh]LB[dg:A]C[Be careful with this shape (sometimes call an "elephant eye") because it has a glaring weakness at A. It isn't always a bad move - especially if you have many stones nearby to back it up. ]
;B[dg]
;W[ch]
;B[dh]
;W[cg]
;B[ei]
;W[eg]LB[df:A][fh:B]C[I'm not sure what good this move does white, except it induces black to play at to keep white separated. Instead, even B would be better, although you will still have a weak group to manage, black won't have closed off your connection as completely yet. Also, playing at B, white is pushing ahead; in the game, white pushes from behind.]
;B[df]
;W[ef]
;B[de]
;W[ce]
;B[ee]C[In part because of the bad shape, white gets cut off. And white's pushing from behind means white wasn't gaining many liberties or running out, so the group is almost useless--having a weak group allows black to build some territory in the top while attacking.]
;W[gg]LB[if:A]C[I think white is behind at this point, unless black's top can be reduced. This move aims at saving the 3 white stones, which aren't doing anything (no infuence, not cutting, no eyes). Perhaps white can threaten to connect up with them later to help your invasion, but this just allows black to enlcose more area at top. Maybe A is a bit better? If black cuts white off from the E14 stones, white can run away and reduce.]
;B[if]
;W[nd]C[You read the ladder right, but if this stone doesn't capture something it has no future.]
