As a normative translation what is written above is correct, but you'd never say that in Irish really. Each language has its own cognates and idioms. To express love in Irish is no different in that sense regarding its own idioms. One of my particular favourites is..
Mo ghrá go daingean thú.
It's from an eighteenth century poem called Caoineadh Airt Uí Laoire and it expresses that notion of connection and timelessness of true love, although is rendered practically meaningless by a literal or normative translation. I would go for something that is more layered in meaning in a diplomatic and idiomatic sense rather than the literal, but the former translation is correct if you choose to use it.
Obviously a superior suggestion, though I would argue ceangailte leis an grá has more meaning in Irish than you seem to imply. I could have said "tríd an" but I thought that would have been too literal.
