I'm Shia and speaking with someone who is also Shia for marriage we met through a muslim marriage app and are South Asian Pakistani/Indian, he is 2-3 years younger than me. Within the first few weeks of us speaking he was upfront with me and told me he was in a 7-8 year relationship with a Sunni girl. They had planned to marry but, her parents were not willing due to the sect difference which dragged on for some time until he ended it. Since they were in different states they would fly to each other to visit and in order to make it halal and for peace of mind he suggested Mu'tah and she agreed. Although they were intimate prior to that for a few years, they were living with their respective families back in the home country and at that time did not do Mu'tah. He said the reason for doing it here in the US once they each moved here for work was because he wanted to make it halal as the eventual goal was marriage and if one of their planes crashed or something happened during travel etc at least he would have the peace of mind knowing it was halal. I spoke with his ex later on and she also attested to this. I want to get married with him but, my parents are considering this a huge red flag that he's engaged in Mu'tah before and it's become a reoccurring topic of argument in our home as a reason to not get married to him when I bring him up. Reason being, that my parents consider it taboo and a way to engage in haram without the strings of a documented marriage attached aka no documentation=there could be multiple women and he's lying or that he might do it again in the future after nikkah. He's spoken to my parents about this as well openly and told them the same when they asked him and was clear that his ex was his only relationship and the only person he's done that with as the end goal with her was a nikkah which because of parents and personal differences did not end up happening. He also stated he does not plan on doing mu'tah after having his nikkah and also does not plan on getting married to anyone else. I guess my question is, am I overlooking a huge red flag and being too nonchalant about all this? Does this mean he is fooling me? I'm not sure. Otherwise, his qualities as a future husband are apparent and positive. I also suppose this question is more geared towards women? Please let me know your thoughts/opinions/further questions to form an opinion?
