To combine your two ".paf" files, you need to use the EXPORT feature, the IMPORT feature and MATCH/MERGE feature.
Open the .paf file that you want to add the information to. This will be your main .paf file when you are finished. Make a backup copy of your main.paf file. You may need this in case something goes wrong or are not happy with your results.
Open the .paf file that contains the information you wish to move over into your main.paf file. Click on FILE|EXPORT to create a GEDCOM file that contains all the individuals you wish to move into your main.paf file. To ensure you get ALL the notes, sources, etc., select ALL of the options on this screen. Save your GEDCOM file and remember where you saved it :-).
Open your main.paf file, click FILE|IMPORT and locate the GEDCOM file you created above. Click IMPORT.
Now, use the MATCH/MERGE feature to link duplicate individuals. This will be your husband, yourself, children and possibly both sets of parents for yourself and your husband. This, of course will depend on how many duplicates you had in each separate file before merging, and which .paf file you made the main.paf file. A good tip is to make a note of those duplicates before you start.
If you have duplicate sources, use the Merge Duplicate Sources " feature to merge them, too.
Finally, once you are happy with end result you can, if you wish, delete the old .paf file. I would however leave it around for some time until you are absolutely sure of the merger.
