First of all you should NOT do a court marriage.
And before you show this answer to your friends let me tell you the reason I post the videos.
If I did not post the videos the answers would be like a scientific journal long that would take more then 5 pages at least to write and that would be for most people to long to read.

The solution is in the videos themselves if you care to watch for them.
The first video: Where is my husband, guruka basically says: "If you do not know, do not marry" with more explenation. Your ability to worry all the time will disturb the process of the one the guru choose for you.
How the worry process is hindering your marriage [Press "Play it"]: http://cueyoutube.com/#C3bIFu9kXKw,4UYYzbzGk6s,Ria1t15XgGw,sq7INkuMrh8,
Second video: Your "boyfriend" is not your soulmate, your soul is. Once you start work on yourself with doing amritvela and start reading from your guru the sri guru granth. That boyfriend of yours will not go to the other side with you after death etc. With more explanation. Don't marry your boyfriend to get against your parents etc. That attractive boyfriend of yours will not look as attractive in 7 years etc.
Third video: I'm aware that this video is told as the existance of kundli and manglik are not effecting the decisions of the parents involved but this video is still relevant. First it should be Paragatt (open). Do a hukumnama. The question your parents have to ask themselves is who is greater, the pandits wisdom or the guru when it does come to the hukumnama. Love comes and goes. The meaning of anand karaj is deeper then Namus or an alliance of two families for the survival for the next generation or by marriang upwards.
The vidoes are relevant to your question. However, I will be using CUE Youtube list for future reference when answering so that answers will be more "compact".
Im copying my answer from http://answers.sikhnet.com/question/9693/kundi-matching-manglik-dosha/
Now before we adress the issue of Manglik.
Love may be well, but unlike what bollywood and hollywood tells us it is not the only thing that will sustain a
healthy marriage. I recommend these videos for yo. Especially the 2nd "Having Relationships" in your case.

MEANING OF MANGLIK IN PUNJABI
Do not forget to ask the very same pandit on what the meaning of manglik is.
Why should we listen to people on the road who to marry when they can not lift themself up from the streets?
