Can gay people go straight?

So first of all I am bisexual and married to a man but have had female relationships in the past. I know there are some people that Claim that being gay is a choice and ive never understood that after the whole attack in Orlando I was researching the topic and I found this article that states that those that don't like the fact that they are gay can infact change it. I don't really think ide believe it tho since I for example love my husband and don't think I could ever be trained to not like men ide just hide it but ide always be interested and miss it. such a complicated topic I guess but was wondering if anybody thinks this is even legit or has heard about this kind of therapy?

here is the link for my source if you can't open it just Google ABC news gay become straight
