I considered that too, having been married to an Egyptian, who ultimately Liked me, but liked my chance of giving him a visa more. I was married for 8 years and did all of the running around for visas etc to bring him over here.
I also have a friend who married someone on a student visa, and he massively took the piss too. It wasnt exactly a marriage of convenience in either case - we both were in relationships, but we both were vulnerable to the love bombing that occurred as it was a relationship with a big fucking bonus for them.
I could see my ex behaving like this, although he was definately not aloof to my family, he was quite the opposite. But he would have been, and was in many times, the same regarding perceived lack of respect and his own pride. And he too would have done alot of the running around for me, cooking, allegedly supporting my studies (so long as it didnt impact him to do boring stuff like childcare) but the main issue was the knowledge that I was not a priority to him, that I wasnt in first place like I had made him, for me. He was young, immature and selfish, and had no idea, due to his culture, at how to have an equal relationship. We divorced when my daughter was 2. Most of his friends who I met, who equally married with visas, divorced after similar amounts of time, usually up to a couple of years after the right to remain was granted
During relate and the psychological therapy I had, it was pointed out that you needed 2 people to fight for a relationship, and that I was the only one effectively IN the relationship.
