I fairly frequently recommend Gouge's book "Of Domestical Duties" (RHB reprint of three volumes under the title "Building a Godly Home"), and I think it's worth recommending again
In the second portion, under marriage, after spending time determining who is eligible to be married and what the requirements are (Equality in years, estate, condition, piety, and religion), he goes on to say
"A first liking is sometimes on the parents' or other friends' part, and then made known to the party to be married, as the friends of Rebekah, liking the offer of Isaac which was made by Abraham's servant, made it known to Rebekah herself (Gen 24:58). Sometimes again the first liking is on the party's part that is to be married, and then if that party be under the authority of parents, the matter must be proposed to them, before there be any further proceeding, as Samson, who, seeing and liking a daughter of the Philistines, told his father and his mother (Judg. 14:2). even if the party is not under the authority of any, it is very fitting that counsel be taken of wise and understanding friends, that in a matter as weighty as marriage, there may be advice of more heads than one, for the preventing of what might happen through rashness.
"After a liking is thus taken by one party for a good mate, that liking must be proposed to the other party so liked, to know whether there is a reciprocal affection of one towards another. Thus Samson went and talked with that woman whom he liked to be his wife (Judg. 14:7).
"If at first there is a good liking mutually and thoroughly settled in both their hearts for one another, love is likely to continue in them forever, as things which are well-glued and settled before being shaken up and down will never be torn apart, but if they are joined together without glue, or shaken while the glue is moist, they cannot remain firm. Mutual love and good liking of each other is as glue. Let the parties to be married be well settled before they come to meet with trials through cohabitation, and that love will not easily be loosened by any trials."
Now I would add that I agree with Edwards that love is also a conscious decision, not just a feeling. But a mutual attraction is definitely recommended, whether that is attraction to character or physical appearance. The second can often follow the first.
