I am not sure what you mean by “external pressures” unless you are referring to what is called a shotgun wedding.
Please understand a few things:
- having grounds for a decree of nullity is not the same thing as getting a decree of nullity. It may appear that you have grounds,(which will not even be examined until after you have a divorce) but you may find that you cannot obtain sufficient evidence (which can include testimony for witnesses) after you are divorced and have attempted to start the process.
- you not only have to obtain the evidence - possibly physical evidence, possibly testimony from your prior spouse as well as your statements and those of other witnesses, but you have to convince not one but two courts that your evidence proves that there was an impediment existing at and on the day of your wedding.
There is an old phrase that there is never a fight but that there are two combatants. You may be having marital difficulties, They may be due in part to what may or may not be an impediment to the marriage; but they are also in part due to both of you. It is not impossible that there is one purely innocent spouse and one purely guilty; but in most marital difficulties, both sides are contributing to the problems.
I say that not to be harsh, but to be realistic and to hope to bring some light to matters at hand, It is not important to me what the difficulties are which you are experiencing, nor do I want to know, That is the realm for professionals; in part (and usually not a siginificant part) the pastor, but also the part of a trained marital counselor. And the job of a competent, trained marital counselor is not to take sides, and to make the other person change, but to show both paties how their behavior, their choices, and their responses are contributing to the problem(s).
The best advice I sould give you is to assume, right here and now, that you do not have a provable case and that you will not be granted a decree of nullity. Then from that position, you need to decide what course of action or actions you are going to take. Hopefully the two of you will seek counseling, and hopefully, from that both of you will learn more about who you are, who your spouse is, what each of you is doing to contribute to the problems, and what you can do to make a solid marriage.
Often the problems can be solved. They cannot be solved if one of the parties is unwilling to accept responsibility for what they are contributing to the issues. Being a “wounded victim” is a short path to a divorce. There are people who truly are very real victims; but there are far more divorces among couples where either one or both of the parties are unwilling to admit they are part of the problem; until that is done, they cannot be part of the solution.
And note: I say this having done divorce work as an attorney for 12 years.
