He really did! He inquired about her and was impressed by her. He tried to protect her and provided for her. But note, he didn't immediately try to claim her. I wonder, he must have known about the family connection and that he could redeem her because he already knew that there was someone who had the right to claim her first. So I think he had already thought about the possibility. Why didn't he act? Why did Ruth have to make herself vulnerable? I don't know if we can answer those questions but I think they are interesting to think about. All I know if Ruth was guided by Naomi and walked by faith into her destiny (which includes the lineage of Christ!). I think sometimes we can be too nitpicky about a man's pursuit. Pursuit doesn't just look one way. A man could be praying about you or waiting on some sign of interest from you or even waiting for confirmation that only the Holy Spirit can provide. It is so important to listen for that still small voice.
Yes @ bolded another good point.
Now regarding Boaz claiming Naomi
I think it's because another kinsmen was ahead of Boaz that he had to act prudently but he could only act if his interest was reciprocated. Naomi knew that and knew the law so that's why she instructed Ruth on what to do. Boaz could not just lay claim to Ruth with out making sure she would be receptive to him because he is a gentleman (have I not charged the young men not to touch you? Ruth 2:8-9) a godly man, and he is an elder and could not loose face and it would be a betrayal of his kinsmen and fellow elder a great disrespect.

Ruth 3:10-13
10 And he said, “May you be blessed by the Lord, my daughter. You have made this last kindness greater than the first in that you have not gone after young men, whether poor or rich.
11 And now, my daughter, do not fear. I will do for you all that you ask, for all my fellow townsmen know that you are a worthy woman.12 And now it is true that I am a redeemer. Yet there is a redeemer nearer than I.13 Remain tonight, and in the morning, if he will redeem you, good; let him do it. But if he is not willing to redeem you, then, as the Lord lives, I will redeem you.
Ruth 4 1-6
4 Now Boaz had gone up to the gate and sat down there. And behold, the redeemer, of whom Boaz had spoken, came by. So Boaz said, “Turn aside, friend; sit down here.” And he turned aside and sat down.2 And he took ten men of the elders of the city and said, “Sit down here.” So they sat down.3 Then he said to the redeemer, “Naomi, who has come back from the country of Moab, is selling the parcel of land that belonged to our relative Elimelech.4 So I thought I would tell you of it and say, ‘Buy it in the presence of those sitting here and in the presence of the elders of my people.’ If you will redeem it, redeem it. But if you[
a] will not, tell me, that I may know, for there is no one besides you to redeem it, and I come after you.” And he said, “I will redeem it.”5 Then Boaz said, “The day you buy the field from the hand of Naomi, you also acquire Ruth[
b]the Moabite, the widow of the dead, in order to perpetuate the name of the dead in his inheritance.”6 Then the redeemer said, “I cannot redeem it for myself, lest I impair my own inheritance. Take my right of redemption yourself, for I cannot redeem it.

Notice he had to inform him of his rights to the land and to Ruth before 10 other elders and once he refused the claim Boaz could then proceed to claim Ruth as his own.
