The first thing that comes to mind is that you may need some help understanding how to ask for what you most want in the relationship. It sounds like you would appreciate and like more time with her. She seems to be pretty busy with obligations and I am assuming that you guys did not move right back in together. One of the suggestions that i make to couples is that we explore the "Five Love Languages." I'm going to provide you with a brief description of these and also a few links that may be helpful.
#1: Words of Affirmation Actions don’t always speak louder than words. If this is your love language, unsolicited compliments mean the world to you. Hearing the words, “I love you,” are important—hearing the reasons behind that love sends your spirits skyward. Insults can leave you shattered and are not easily forgotten.
#2: Quality Time For those whose love language is spoken with Quality Time, nothing says, “I love you,” like full, undivided attention. Being there for this type of person is critical, but really being there—with the TV off, fork and knife down, and all chores and tasks on standby—makes your significant other feel truly special and loved. Distractions, postponed dates, or the failure to listen can be especially hurtful.
#3: Receiving Gifts Don’t mistake this love language for materialism; the receiver of gifts thrives on the love, thoughtfulness, and effort behind the gift. If you speak this language, the perfect gift or gesture shows that you are known, you are cared for, and you are prized above whatever was sacrificed to bring the gift to you. A missed birthday, anniversary, or a hasty, thoughtless gift would be disastrous—so would the absence of everyday gestures.
#4: Acts of Service Can vacuuming the floors really be an expression of love? Absolutely! Anything you do to ease the burden of responsibilities weighing on an “Acts of Service” person will speak volumes. The words he or she most want to hear: “Let me do that for you.” Laziness, broken commitments, and making more work for them tell speakers of this language their feelings don’t matter.
#5: Physical Touch This language isn’t all about the bedroom. A person whose primary language is Physical Touch is, not surprisingly, very touchy. Hugs, pats on the back, holding hands, and thoughtful touches on the arm, shoulder, or face—they can all be ways to show excitement, concern, care, and love. Physical presence and accessibility are crucial, while neglect or abuse can be unforgivable and destructive.
Those are just a few things to consider in understanding how to give and receive love. This will help you communicate your needs, and if she is able to identify her needs as well, you guys will have a greater chance at success.
Another thing to consider is how you guys have established boundaries in the relationship.setting boundaries is an important part of any relationship. To have the healthiest relationship, both partners should know each other’s wants, goals, fears and limits. You should feel comfortable communicating your honest needs to your partner without being afraid of what they might do in response. If your partner tells you that your needs are stupid, gets angry with you or goes against what you’re comfortable with, then your partner is not showing you the respect you deserve. You have to be willing to offer the same however.
She has been wounded by the possibility of infidelity. I encourage you to allow her to communicate her fears about this. You may want to make sure that you are not defensive as she talks to you, this may lead her to feel resentment toward you.
If you feel that you would like more time with her, ask her how you can help her balance her obligations, or even participate in some of the activities with her and her children.
