Thank you for your follow up.
Texas is a community property
state, so generally as long as the house was purchased during the marriage, your would be entitled to half of the equity in the house and also to half of any other marital assets that had been acquired during the marriage.
Also, you might be entitled to a durational alimony
, but given the short term of the marriage, such alimony would only be limited to 2-3 years after the divorce.
Unfortunately, if your husband wants to file for a divorce, there is nothing that you can legally do to keep him married to you, as the court cannot force people to stay married who want to divorce.
Also, unfortunately, when it comes to marriages, the law does not provide any type of compensation for emotional pain / suffering sustained during the marriage, as people enter into marriage and stay married voluntarily and always have an option of obtaining a divorce.
I would strongly suggest that you do document your husband's infidelity
and consult and retain local divorce attorney, who will be able to evaluate your entire situation and will fight for your legal rights and interests in your upcoming divorce.
I am once again very sorry that you are in this difficult situation and I wish you the best of luck!
