Gos. Phil. is not like one of the NT Gospels. It is a compilation of statements in a variety of literary types: parable, paraenesis, narrative dialogue, dominical saying, aphorism, and analogy, along with samples of biblical exegesis, dogma, and polemics. These statements, however, are not placed into a narrative framework but are arranged in a sequence that is neither strictly topical nor predictable. Efforts to analyze the scheme of arrangement are hampered by inconvenient lacunae in the ms.[Isenberg, W. “Philip, the Gospel of” in The Anchor Bible Dictionary ed.

So trying to use this text to suggest that Jesus and Mary were in fact married seems to be stretching the imagination into the realms of pure illusion. The text can only be constructed via guess work and even the constructions given don't prove or even suggest that Jesus was married. They merely hypothetically suggest that Jesus on a particular occassion showed Mary affection. Something the early Church was prone to do [Rom 16:16; 1 Cor 16:20; 2 Cor 13:12; 1 Thess 5:26; 1 Pet 5:14].
Another text used in support for Brown’s illustrious theory is that of the Gospel of Mary. The text is dated to the late second century and is also plagued with the problem of missing fragments. Pheme Perkins explains that:
What remains of Gospel of Mary consists of the ending of two separate revelations held together by a frame story about the gathering of the apostles after Jesus’ ascent to the heavens. The first revelation is a dialogue between the risen Jesus and his disciples. The second is Mary’s report of a private vision and its interpretation that the Lord had granted her… Instead of fulfilling the commission, the disciples despair over the suffering that surely awaits them. At this point, Mary reminds them of the Lord’s grace and protection. She alludes to their restoration to their true gnostic identity, “he has prepared us and made us into men” (cf. Gos. Thom. 114; and “put on the perfect man,” Gos. Phil. 75: 20–35). Peter requests that Mary recount a revelation that she had had from the Lord which was unknown to the apostles.[Perkins, Pheme “Mary, the Gospel of” in The Anchor Bible Dictionary ed.
